How to do it yourself?

  • PVC pipes (inner diameter. 15-20mm);
  • PVC tees. 2pcs.
  • PVC corners. 4pcs.
  • Stainless steel clamps. 4 pcs.
  • Pump (quantity and power depend on the volume and population of the aquarium);
  • Hose;
  • Screwdriver.
  • Measure the length and width of the aquarium.
  • Consider the design of the filter so that the tubes cover as much of the bottom area as possible, spreading evenly. The system should turn out to be closed.
  • Cut PVC pipes of the required length and in the required quantity (in this case, it is recommended to calculate the size of the filter so that about 2 cm remains between it and the walls of the aquarium.This will allow you to further mask the tubes with soil and gravel).
  • In accordance with the previously thought-out design, assemble the filter frame; first, using corners, two external sides of the structure are assembled (1 long and 2 short tubes are connected), then two U-shaped structures are connected to each other using a tee.
  • Another long tube is inserted into the free holes of the tees (it divides the frame rectangle in half).
  • Using a screwdriver, drill through holes in the tubes (diameter. no more than 5 mm) every 4 cm.
  • Connect the pump to one of the tees using clamps.
  • Install the filter frame to the bottom of the aquarium, attach a hose to the pump and take it to the phyto filter.
  • Sprinkle the structure with washed gravel and coarse soil, fill with settled water.

All about the bottom filter: a clean aquarium without unnecessary equipment

The bottom filter is one of the most controversial inventions of aquarists.

Many consider it an ideal solution for maintaining the natural balance of the ecosystem, others point to the complexity of its maintenance and not always correct operation.

Nevertheless, bottom filters have been very popular for a long time and are still of interest. What is this filter and what are the advantages and disadvantages?

How to install in an aquarium?

  • It is necessary to prepare the aquarium for the installation of the bottom filter. If it is already inhabited, it is necessary to carefully transplant the inhabitants into pre-prepared temporary housing, drain the water, remove all accessories, plants and soil.
  • Install the required number of filter grates at the bottom of the aquarium (most often, the shape and size of the bottom filter can be changed in accordance with the dimensions of a particular aquarium; it is necessary to specify the number of sections in the selected model when purchasing).
  • Connect the sections to each other with hook locks.
  • Install the airlift (telescopic tube), adjusting it according to the normal water level in the aquarium.
  • The airlift tube can be connected to a pump or air compressor (connecting to a pump increases efficiency).
  • Fill bottom sections with coarse soil (fraction of at least 5 mm) and small stones for stability.
  • Pour water into the aquarium.
  • It is recommended to run the filter for the first time under increased load.
  • It is better to add aquatic organisms to the aquarium after installing the filter gradually, little by little at a time.

Fluval

Fluval. have a standard design (prefabricated plates, airlift and adapter). They are in great demand due to their low cost. Reviews of these filters are controversial: ideal for small aquariums, but often defective and too fragile.

Principle of operation

The false door system is simple:

  • With the help of a pump, water from the bottom of the aquarium is transferred to the upper layer through special transparent tubes.
  • The liquid passes through the filter material (sponge) and then is discharged back.
  • On the way back, the water is once again purified by soil.
  • And the process repeats again.

Top 3 manufacturers

Resun

Resun. consists of several filter plates, two airlifts and a conductor. It copes well with cleaning the bottom in small and medium-sized aquariums, but itself does not need cleaning for a relatively long time.

The main disadvantage is fragile plates. Average.

HAILEA

HAILEA. consists of several filtering sections (714 cm) and airlift for air supply. Very practical and versatile design, perfect for non-standard connections.

There is a system for connecting to an external filter. Reviews are only positive. It successfully combines reasonable price and high quality. Medium (depends on the number of sections included).

pros

  • Decorativeness. Due to the fact that the pipes take up little space, and the false bottom is thin, the pump will be the only noticeable part of the structure. It can be disguised with sweet clover plants or decorative stones.
  • Biofiltration. In the case of direct filtration, the purifier is not only the cassette or filter sheet, but the soil itself. It will trap organic particles, which will turn into a nutrient substrate for melilot plants.
  • Aeration. Additional enrichment of water with oxygen both during direct and reverse filtration prevents water stagnation and creates comfortable conditions for fish.
  • Profitability. This design is inexpensive, even if you purchase a finished product. Costs will be reduced even more with the self-production of a structure from PVC pipes.

In the usual

Drain half of the water from the aquarium, transfer the fish to a temporary container and drain the rest of the water. Install a pipe structure on the bottom if you have a pipe filter. If you purchased a false bottom design, attach the pump with a cassette filter to the bottom of the bottom and place the bottom on the supporting legs. Attach a water drainage hose to the pump, fix it on the inner wall. Lay a filter sheet on top of the false bottom or tubes, if you are not using a cassette, lay out decorative stones, sprinkle them with soil, then fill the aquarium with water.

Manufacturing steps

  • Connect 1 long pipe and 2 short pipes together so that they form 3 sides of a rectangle. Use corners for this.
  • Assemble a similar structure from 1 long pipe and 2 short.
  • Fasten the frames to each other using tees so that a rectangle is formed with 2 solid and 2 prefabricated short sides.
  • Insert a third long pipe into the free holes of the tees, dividing the rectangle in half.
  • Drill 5 mm through holes in the pipes every 4 cm using a screwdriver.
  • Attach the pump to one of the tees using clamps. You will get the following construction.
  • Install the resulting filter at the bottom of the aquarium, connect a hose to the pump outlet and take it to the phyto filter.
  • Sprinkle substrate on the structure and fill the aquarium with water.

bottom filter manufacturing

Back

This method is more effective due to the fact that the pump is installed in the cavity under the false bottom and pumps water in the opposite direction. from under the ground into the body of water.

Tools and materials

You will need:

  • PVC pipes 65 cm. 3 pcs.;
  • PVC pipes 20 cm. 4 pcs.;
  • PVC corners. 4 pcs.;
  • PVC tees. 2 pcs.;
  • stainless steel clamps. 4 pcs.;
  • pump for 2800 l / h. 1 pc.;
  • hacksaw;

How to install a bottom filter in an aquarium

The installation and reinstallation process is carried out by completely restarting the reservoir, since to install the filter, you will have to drain the water and transplant all residents into another container.

Bottom filter for an aquarium: how it works, is it possible to do it yourself

Advantages and disadvantages

This uncomplicated water purification system has its positive and negative sides.

Bottom filter design

This type of filter is an unusual system. It consists of

  • lattices with fine meshes (or from a thin plate with small holes),
  • pump
  • tube systems.

The tubes are located at the bottom of the aquarium, a grate or plate is laid on top, and then a layer of soil.

When installing the bottom filter, small pebbles or small stones are poured on top.

How the bottom filter works?

  • the pump pumps out water from under the grate,
  • then it is cleaned through a special filter element and returned back to the aquarium;
  • then the water seeps through the ground again, undergoing rough cleaning, and the process starts over.

In the pipes, which are located at the very bottom (under the plate), there are small holes through which water is taken. Optionally, you can additionally install a tube with an aerator. Thus, not only filtration will be carried out, but also aeration of the entire soil.

Disadvantages of the bottom filter

In addition to the pluses, the false door also has disadvantages:

  • The surface of the soil still contains large amounts of dirt and debris that cannot pass.
  • Debris clogs up the holes in the pipes very quickly. To clean them, all the water is poured out of the aquarium and the structure is disassembled.
  • Not recommended for aquariums with a lot of algae.

The bottom filter cleans water well from various impurities. To acquire it, you need to think carefully, because it has both advantages and disadvantages.

Benefits of the bottom filter

This filter has certain advantages:

  • With its help, the circulation of water in the aquarium occurs continuously.
  • Passing through the ground, water does not linger there for a second.
  • Constant water movement does not allow the aquarium to quickly become dirty and does not allow various infections to appear.
  • Such a false thing is completely invisible under the plate.
  • An optimal microclimate is created for fish.

How to make a bottom filter yourself with your own hands.

There are several ways to assemble the structure itself. The most optimal of them is the method using conventional plumbing plastic pipes.

The length and width of the aquarium are measured. Based on these parameters, it is calculated how many meters will be required to manufacture this system. It is better to take a small diameter plastic pipe (up to 3 cm).

So, for the water intake system you will need

  • 3 main pipes (their length corresponds to the length of the aquarium itself),
  • 4 connecting brackets,
  • 2 tees
  • 4 small sections (these will connect the main tubes),
  • you will also need a plastic separator and a small funnel (a filter will be installed in it).

You can take plexiglass as a lattice, cut out the desired size and make holes with a drill (it is better to do this with a soldering iron, because during the drilling process it can burst).

After assembling the pipes into the desired structure, holes should be made in them as well. The pump that will pump water is installed on the main pipe. Accordingly, the closer the holes are to it, the stronger the thrust will be. To ensure that the water is pumped out evenly from all sides, it is best to drill a little more holes on the opposite side of the pump.

So, the pipes are soldered together, plexiglass and the main pipe with a pump are installed on top. When the whole structure is assembled, after a couple of hours it can be installed in the aquarium. After its installation, the soil is poured from above and water is poured. The system is then turned on and tested for several hours. And finally, you can please the result of the inhabitants of the aquarium.

It should be noted that in this case sand and fine soil cannot be used, because it will clog the holes through which the water is circulated.

When installing the bottom filter, small pebbles or small stones are poured on top.

What can be done?

Making such a device at home will take more time.

  • A round, tall plastic canister can be used as a body.
  • If not, then a piece of plastic garden pipe with a large diameter will do. True, the top and bottom covers will have to be cut and fastened independently.

Progress

First step

  • A hole is cut at the bottom of the canister, where a metal or plastic fitting with a one-way inlet valve is screwed tightly.
  • 2 holes are made in the cover: for attaching the water outlet valve and the electric pump.
  • The pump itself is attached through a fitting to the inside of the cover.

Now you need to make cassettes, or cartridges, with filter elements. They can be made from plastic flower pots by cutting off the upper wide part evenly.

The diameter of such self-made cassettes should be slightly less than the inner diameter of the canister.

Holes are burned in the bottom of each cassette for water passage.

The first cartridge, where the sponge is placed, is inserted into the canister so that its bottom is slightly higher than the adapter with an inlet valve.

Next, a second cartridge is installed, where the filtering material can be fiber, synthetic winterizer or cotton wool. A cassette with a filtering biomaterial is installed from above so that it is below the pump attached to the canister lid.

If the body of the external filter is made by yourself, then its bottom and cover are sealed with silicone or resin.

Tubing or hoses are attached to the inlet and outlet adapters with valves. Their length is adjustable depending on the depth of the aquarium and the distance to the filter.

As in the first case, a working pump creates pressure, under the influence of which water is first sucked into the canister, goes through all the filtration stages and then flows back into the aquarium. Before starting operation, it is necessary to check the canister for leaks within 24 hours by filling it with water.

The main element of the cleaners is the pump. When choosing it, you should take into account the volume of the aquarium. For example: a pump with a capacity of 300 liters per hour is suitable for a 70 liter aquarium, and 1000 liters per hour for a 200 liter aquarium.

How the bottom filter works?

The principle of operation is very simple. the pump sucks water into the tubes through the holes, first passing it through the soil, which in turn acts as a filter element.

With this method of filtration, the emphasis is placed on nitrifying bacteria that live in large numbers in the soil. They convert organic waste to nitrite, which is less hazardous to fish. In this case, the soil layer must be at least 4 cm.

Optionally, you can additionally install a tube with an aerator. Thus, not only filtration will be carried out, but also aeration of the entire soil.

Is there an alternative to the bottom filter?

Many aquarists argue that bottom filters are a thing of the past. Of course, they are quite effective in cleaning the aquarium from contamination, but additional maintenance methods are still required to maintain cleanliness. There are alternative devices: external and internal filters.

Each model is designed for a specific volume of the aquarium. Also filters can include a device for air aeration. a compressor. Such devices are able to pass the entire volume of the aquarium through themselves in literally 10-15 minutes.

The advantage of these filters is quick installation and easy maintenance. To clean it, it is enough to disassemble it and rinse all structural elements under the tap.

Bottom filter design

This type of filter is an unusual system. It consists of

  • soil,
  • pump
  • tube systems.

The tubes are located at the bottom of the aquarium, a grate or plate is laid on top, and then a layer of soil.

Advantages and disadvantages

Before installing the bottom filter, you should familiarize yourself with its features. Of course, the first minus will appear immediately. To install the system, it is necessary to completely drain the water from the aquarium, remove the soil and all decorative elements, which takes a lot of time.

The indisputable advantage of just such a filter is:

  • continuous circulation of water throughout the aquarium;
  • when passing through the ground, it excludes stagnation at the bottom;
  • such a water cycle avoids rapid contamination of the aquarium and the appearance of various kinds of infections.

Aeration of the soil helps aquatic plants to strengthen and develop their root system, however, when the soil is saturated with oxygen, the growth of leaves slows down. In addition, there are no plant nutrients left in the soil, they leave along with the water.

Even when using a bottom filter, dirt particles still remain on the surface of the soil. They do not pass through it due to their large size. Therefore, as mentioned above, you have to wash the pebbles. But you can avoid unnecessary fuss with changing water and flushing the soil.

To do this, you need to install an additional filter element, which will have time to drive all the water through itself. Or you can purchase a device. a siphon, which removes large particles of dirt from the surface of the soil (it is advisable to carry out this procedure weekly).

Another disadvantage of the system is that the holes in the tubes are quickly clogged with debris. To clean them, you need to completely pour out the water from the aquarium and disassemble the entire structure. For a small tank (up to 50 l) this will not cause much problem, but for a large aquarium it is very difficult and tough work.

Aquarium bottom filter

The bottom filter is a complete water purification system that is used in aquariums of various sizes. Its main principle is water filtration in a natural way, that is, through the soil. However, about this method, many questions and disagreements arise, because the main debris remains on the surface of the soil, so it has to be washed periodically. So, let’s look at everything in order.

A bottom filter is an effective way of filtering water, which allows it to be naturally purified (passing through the ground). This type of design has both advantages and disadvantages, which is why many aquarists hesitate to purchase it. But why waste money if you can assemble a bottom filter yourself from inexpensive materials?

This type of filtration was known at the end of the last century, but it is still used today. Difficulties in installation and maintenance force amateurs to switch to more modern methods of water purification using external and internal filters (the latter are attached to the inner wall of the aquarium).

How to install a bottom type filter in an aquarium

Installation of the bottom filter goes through such stages as:

  • removal of water from the container, as well as soil,
  • installation of the frame, it will raise the filter one or two centimeters above the bottom,
  • backfilling the soil back into the aquarium.

The soil needs to be loose so that water quickly seeps through the device. After installation, a constant flow of liquid will begin without stagnation.

Colonies of beneficial bacteria will gradually settle in, which will protect the aquarium from dangerous microorganisms. It is worth remembering to flush the filter regularly every four months.

How to make a do-it-yourself aquarium bottom filter

There are several options for assembling the bottom filter. The easiest is to use plastic pipes for the plumbing. To do this, measure the width and length of the aquarium in order to calculate the required number of meters to create a filter installation. A plastic pipe with a diameter of up to 3 cm is suitable for you.

  • two tees,
  • four connecting corners,
  • three pipes that match the length of the aquarium,
  • small funnel for filter installation,
  • plastic divider.

The role of the lattice can be played by plexiglass.

There are two more very simple options for creating a homemade bottom filter with your own hands.

HOW TO: undergravel jet system. aquarium filtration TUTORIAL

The first assumes the use of a glass jar with a capacity of 0.5-1 liters. It is closed with a lid, holes are made in it for the tube, as well as for the water that will come from the aquarium. Another cover is used as a partition. Filtration material is placed between the lids.

The second option is to use a clay bowl. A material for filtration is placed in it, an ordinary funnel is placed on top of the lining. As a material for cleaning, medium-fraction quartz sand and nylon threads are used. Optionally, you can purchase and supply an aerator.

Despite the fact that such filters are partly outdated, many still continue to use them, because with regular cleaning they effectively purify water.

Internal and external devices are used as an alternative. They are selected for the volume of a particular aquarium, they can also be equipped with a compressor for air enrichment. Powerful filters can pass the entire volume of the aquarium in just ten minutes.

Aquarium bottom filter. design pros and cons

Bottom filters are a simple system for water purification; they can be used in containers of different sizes. Cleaning is carried out naturally. with the help of soil.

True, it also has a drawback. pollution accumulates on the surface of the filter material, and it needs to be washed from time to time.

The design of such a device consists of such components as:

  • water pump,
  • small mesh lattice,
  • tube systems.

Tubes are placed at the bottom of the container, a grate is installed on top, and then a layer of soil. It is worth remembering that fine soil or sand will not work, as they will clog into the mesh holes. Use small pebbles or pebbles instead.

Principle of operation

The system works according to a fairly simple scheme.

Water is pumped out from under the grate through the pump. Then it passes through the filter material and is discharged back. At the next stage, the water is purified from coarse soil contamination, and then the process is repeated.

The pipes located at the bottom have holes for suction of water. You can also put a tube with an aerator, which will provide both cleaning and enrichment of the soil with oxygen.

Before installing such a filter, you need to understand that you will have to drain all the water, remove both the soil and all the plants from the aquarium, after which you can start installation.

  • compactness,
  • quiet work,
  • continuous circulation,
  • no stagnation of water,
  • the water cycle protects against contamination and the spread of infections,
  • affordable construction price,
  • high level of mechanical and biological treatment,
  • invisibility of equipment,
  • creating an optimal microclimate for fish.

Aeration of the soil will allow the algae to grow faster and strengthen the roots. However, it is important to avoid oversaturation of the soil with oxygen, which leads to a slowdown in the growth of leaves and the departure of substances necessary for plant growth from the soil.

Therefore, such a filter is not used in large aquariums with a large number of plants.

Disadvantages of bottom filters

Installation of aquarium bottom filters does not provide 100% cleaning, some of the contamination settles on the ground and does not pass through small holes. In this regard, it is necessary to wash the stones manually or install an additional filtration element for driving water.

The disadvantages include the fact that the tubes quickly fill up with dirt. To clean them, you will again have to pour out the liquid and completely disassemble the device. If the capacity of the aquarium is small, it will not take much time, and in the case of a large capacity, it is difficult and painstaking work.

In small aquariums, the pump will have enough power to ensure an even flow of water. In larger containers, bottom filters do not always cope with their task, because the water has to overcome resistance. Sometimes she does not succeed, and the purified liquid remains at the bottom of the aquarium.

Some models have a gap between the filter plate and the aquarium glass. This leads to the fact that small fish fall under the structure and from there it is often necessary to extract the dead small inhabitants of the aquarium.

How to put the bottom filter in the aquarium correctly

Review and rating of the best bottom filters

Aquarium bottom filter. pros, cons and how to do it yourself?

Principle of operation

The principle of operation of the bottom-type cleaning device is:

  • A pump located under the grill draws in water.
  • Passing through the soil, water is filtered, getting rid of dirt, bacteria.
  • Liquid returns to reservoir.

The filter in the aquarium works using a natural method: nitrifying organisms living in the substrate recycle organic residues. When using a bottom-type device, the soil layer should be equal to 4 cm or more.

Some aquarists improve the filter’s performance by equipping the device with an aerator, which results in both filtration and aeration in the aquarium.

Bottom filter structure

An aquarium bottom filter is also referred to as a “false bottom”. The structure consists of:

  • the soil;
  • water pump;
  • lattice plate;
  • tubules.

A set of tubes is placed at the bottom of the reservoir, a lattice is laid on them, and then the structure is covered with soil. It is important to note that when installing a false bottom, sand or a substrate of a fine fraction is not used, otherwise the grille of the device will clog and the device will not fulfill its intended purpose. In artificial reservoirs with a bottom type cleaner, it is better to use small pebbles or pebbles as a substrate.

It should be noted that models of bottom filters are on sale specifically for round and cylindrical reservoirs. The principle of installation of purifiers in ball-shaped tanks is identical to installation in a rectangular reservoir.

Advantages and disadvantages

Before you buy or make a bottom filter at home, you should find out about the advantages and disadvantages of the device. The advantages of a false door are:

  • Constant circulation of the aquarium liquid.
  • Stagnation is avoided due to the regular passage of water through the soil.
  • Continuous circulation reduces the level of pollution of the reservoir, so the likelihood of the development of harmful bacteria and microbes is reduced.
  • Since the filter is covered with soil, the device does not spoil the appearance of the reservoir.
  • An optimal microclimate is created for fish.
  • To install the device, the substrate, decorations and residents are removed from the tank, the water is drained.
  • During the operation of the device, useful and nutritious elements are washed out of the soil, so root plants grow more slowly.
  • Even when operating at full capacity, the device cannot cope with all contamination, so particles of debris remain on the surface of the substrate. Aquarists using bottom cleaners regularly siphon the soil to remove dirt.
  • The tubes included in the device are clogged with debris. To clean the tubes, remove fish, decorations and water from the tank, disassemble the structure and clean the elements.
  • The design of certain models implies the presence of space between the grate and the elements, where small fish, snails and shrimps can get.

Given the disadvantages of the devices, we can conclude that it is better to choose a bottom filter for a round aquarium or a standard rectangular reservoir with a capacity of no more than 60 liters. Avoid false bottom installation in tanks with many root flora, as well as in large tanks.

DIY bottom filter

You can build a bottom filter for an aquarium yourself using the tools at hand. There are several methods for constructing the device, but it is better for a beginner aquarist to choose the simplest one. the method using plastic water pipes.

READ  How to feed your fish in an aquarium

First, the dimensions of the artificial reservoir are measured: length and width. These indicators are needed to determine the length of the tubes. For manufacturing you will also need:

  • Plastic water pipes. 3 pcs. (pipe length is identical to the tank length).
  • Connecting corners. 4 pieces.
  • Tee. 2 pieces.
  • Plexiglass. 1 piece.
  • Pump. 1pc.
  • Slices of tubules. 4 pieces.
  • Separator. 1 piece.
  • Small funnel for filter. 1 piece.

To build a filter purifier, you must first make a filter grate. To do this, take plexiglass, in which holes are created with tools. In addition to holes, a round hole is drilled in the glass for a tube with a pump. Having finished with the manufacture of the lattice, they begin to assemble the device.

How to make a do-it-yourself aquarium bottom filter:

  • The tubes are assembled into a structure, while holes are made in each.
  • A pump is placed in the main tube. It should be noted that the closer the holes are to it, the more powerful the intake of liquid will be.
  • The tubes are soldered, a previously made grate and a tube with a pump are placed on top.
  • After assembly, the device is left for a couple of hours and then installed.
  • After installation, the device is covered with soil, turn on and pour liquid into the tank.
  • The system is checked for suitability for a couple of hours, and then the fish and other residents are launched.

Bottom filters are purification devices for home artificial reservoirs, the main advantage of which is the natural method of water purification. In addition, the false bottom does not spoil the appearance of the tank, however, along with the advantages, the device also has a number of disadvantages that confuse aquarists. The best solution would be to assemble the bottom cleaner with your own hands. this will help save money and check the operation of the device personally.

What is required for manufacturing?

To make a high-quality filter for an aquarium, you need to understand the basic requirements for it: not only purify the water from dirt particles, but also enrich the water with oxygen. Often, pharmaceuticals are immediately added to the device, which will have a beneficial effect on the life of the inhabitants of the aquarium. All filters are usually subdivided into several categories, so the list of used materials at hand is determined depending on the chosen design. Let’s get acquainted with them in more detail.

  • The bottom filter, as the name suggests, is located right at the bottom of the fish dwelling. It has a large number of holes from which air enters, as a result of which water is purified from turbidity. The bottom filter must be installed even before the fish populate and the tank is filled with water.
  • The internal filter is fixed inside the aquarium. It is a combination of a filler placed, for example, in a plastic bottle, and a compressor. This variety quickly becomes dirty and no longer cope with the work, therefore it requires regular checks.
  • External filters are a lot like internal filters, but are placed outside the aquarium.

How to make?

How to make a DIY aquarium filter?

What can serve as a filler?

To begin with, there is another classification of filters, depending on what kind of filler is used and what contaminants the water is purified from.

  • Mechanical cleaners remove turbidity and floating particles that rise from the bottom due to the compressor and the movement of the inhabitants of the aquarium. Such dirt, decomposing, gradually forms turbidity, therefore, you cannot do without a filter.
  • Chemical filters help purify water from organic substances, that is, nitrates or phosphates. Like mechanical devices, they require regular cleaning.
  • Absorption-chemical filters cope with waste from aquatic life. They are necessarily washed under running water.
  • First of all, we are talking about foam or synthetic winterizer parts, for example, a sponge. It is cheap, it can take any shape and simultaneously work as a biological and mechanical filter. However, the pores are an ideal breeding ground for bacteria, which cannot be called an advantage of this material. Regularly, the sponge will have to be washed from mucus and sludge, and also changed quite often.
  • Filter wool is also considered an inexpensive material. Its advantages include reusability, ease of cleaning, and reliability. It is better to use cotton wool at the final stage of mechanical cleaning.
  • Bioballs are made of plastic. On the move, they uniformly wash the filter media and provide a good basis for the settling of the necessary bacteria.
  • The sintered glass is sold in the form of small balls, which are about 14 millimeters in diameter. During the baking procedure, they develop pores in which beneficial bacteria appear.
  • Zeolite is a very cheap material that perfectly absorbs all ammonium from water. Thanks to this sorbent, it will be possible to quickly eliminate nitrates in water.
  • Carbon filler is quite often used for filtration in an aquarium, but only under certain conditions. Activated carbon with small-diameter granules and sufficient pore size to absorb dirt and turbidity is suitable. It is recommended to use carbon filler only in a newly launched aquarium.
  • A good solution is to use peat. as natural, efficient and budgetary as possible. This material not only reduces the number of fungi, but also lowers alkalinity.

Important! The filler can also be sandy. In this case, river quartz sand is simply washed and boiled. We must not forget about synthetic fabrics, for example, nylon or nylon.

Interior

Homemade aquarium internal filter can be made in different variations. For example, to create it you will need a plastic container with a lid, for example, used for storing cereals, a regular sponge or thick porous material, a sealed water pump with a fitting that can be attached to the container lid, a material for biological filtration, and several suction cups with adhesive resin. Biological filtration can be carried out using ceramic rings or granules or ordinary cotton wool. It is worth adhering to the following algorithm of actions:

  • holes are cut along the entire perimeter of the container on the edges; their main purpose will be to absorb water;
  • further, a sponge is placed on the bottom, which will deal with the rough cleaning of the liquid; directly on it is a material that contributes to fine water purification. ordinary cotton wool or materials for biological filtration;
  • a hole is created in the container lid, corresponding to the diameter of the delivery nozzle; the latter is hermetically inserted into the hole and additionally fixed with resin or silicone;
  • a pump is fixed on the fitting, the task of which is to create compression inside the container;
  • finally, several suction cups are glued to the top of the sidewall of the container;
  • the finished filter is either placed on the bottom of the aquarium or fixed from the inside on the wall of the container; if the pump outlet is supplemented with a plastic nozzle with a tube, it will also be possible to provide aeration of the aquarium contents.

External

An external aquarium filter is as easy to make as an internal filter, but it will take a little longer. It is recommended to use a high plastic canister or a piece of a wide diameter garden pipe as the main container. So, the production of an external filter will be carried out as follows:

  • first of all, a hole is cut at the bottom of the canister, and a fitting with a one-way valve is inserted into the resulting hole; the part can be made of plastic or metal;
  • further, several holes are cut in the cover, in which the electric pump and the water outlet valve will be located;
  • the pump is fixed on the inside of the cover so that the fitting easily enters the prepared hole;
  • further, you will have to combine all the filter material in small cassettes, whose diameter will be slightly smaller than the diameter of the canister; it is convenient to collect them from plastic flower pots, the extended top of which is cut off;
  • a hole for water is cut in the bottom, and the cassette itself is filled with filter materials;
  • the first cartridge can be filled with a sponge, and then placed in the canister so that it is slightly higher than the adapter equipped with a release valve;
  • the second cartridge is filled with fiber, cotton wool or synthetic winterizer or other material for biological filtration; inside the canister, it is fixed in such a way as to be below the pump;
  • additionally, the body should be sealed with resin or silicone; adapters are fixed with tubes or hoses, their length is determined from the depth of the aquarium and the distance at which the filter is located;
  • the external filter will work due to the pump; the latter will create pressure, which promotes the suction of the liquid into the canister, and the water, after going through the filtration steps, will return to the aquarium.

Starting work with an external filter, you should first carry out a test mode for a whole day to make sure that the canister used is absolutely tight. The pump should be selected depending on the volume of the aquarium itself.

If the volume of the tank corresponds to 70 liters, then it is better to take a pump with a capacity of 300 liters per hour, and for a 200-liter aquarium, a capacity of 1000 liters per hour is required.

Donny

The bottom filter works by using the correct soil. Water passes through a sand or similar filter, thereby being roughly purified. To manufacture the device, you need a pump, conventional tubes and tubes with holes, and a compressor. The manufacturing process is as follows:

  • parts with holes are laid under the ground, and a plastic mesh with small holes is placed on top of them; its task will be to prevent soil from entering the holes of the pipes;
  • the pump or compressor is fixed close to the surface.

Regardless of the design chosen, the filter must be cleaned regularly. If you neglect this procedure, then at first he will cease to cope with the task at hand, and then he will generally begin to pollute the water. The frequency of cleaning is determined as needed, namely:

  • the smaller the device itself and the greater the amount of work, the more often the procedure should take place;
  • the need for flushing, as a rule, signals a deterioration in the quality of water purification.

Important! Small filters will have to be rinsed once a week, while large structures will need to be rinsed once every few months. Water at room temperature must be used.
