Do-it-yourself reverse osmosis for an aquarium

In freshwater aquariums

Even those new to the aquarium hobby are well aware that every fish species needs an aquatic environment with specific pH and hardness values. Therefore, after filtration by reverse osmosis, the parameters are adjusted to acceptable values ​​and the necessary micro and macro elements are added.

Total water treatment is especially appreciated by lovers of aquarium invertebrates. Their pets do not tolerate the presence of gases and metals in the aquatic environment. So, even a small amount of copper depressingly affects snails and crustaceans. At the same time, they need calcium for growth and development.

Reverse osmosis for aquarium

The water in the aquarium is for fish and plants the same habitat as the air for us. Fish are uncomfortable in water that does not meet certain requirements. The liquid supplied to the tap from the central water supply system is far from ideal in its composition. Therefore, in order to use it directly from the tap for a change in an artificial reservoir, you will need to normalize it by removing all harmful components from it. solid and liquid. It is for this purpose that osmosis is used for the aquarium.

In saltwater aquariums

For saltwater aquariums, the use of an osmotic water base is mandatory. After all, the absence of nitrates, phosphates and sulfates in the water is important for them. The marine aquatic environment is prepared as follows: a mixture of various additives is dosed into a liquid filtered by reverse osmosis.

Important! When osmotic water treatment for tanks with a marine aquatic environment, special cartridges that enrich the liquid with minerals, silver ions and other substances must not be used.

Features of use

If, in the process of preparing a water base for aquariums, it is filtered by osmosis, you need to know about some of the features of its use.

Today, reverse osmosis is considered the most efficient and advanced technology used for water purification. The main purpose of the method is to remove all impurities from the water and reduce its hardness to a neutral level. After such filtration, it is purified by more than 90% of all minerals. Since a sharp change in the parameters of the aquatic environment from “poor” to ideal affects the condition of the inhabitants of an artificial reservoir, it is advisable to mix osmotic water with tap water, passed through a charcoal filter. At the same time, use different chemistry to obtain the desired composition and remove chlorine.

A reverse osmosis filter for an aquarium is certainly used by those who breed different types of cichlids. This tropical fish needs soft, acidic and completely purified water for successful breeding in captivity. Plant lovers who prefer a herbal aquarium use osmosis to soften the water. Vegetation grows well in herbalists with reduced water hardness.

Benefits

Osmosis in an aquarium has several advantages over other filters:

  • The maximum degree of purification of tap water, the elimination of all chemical constituents from it, as well as viruses and bacteria. This degree of purification is guaranteed only by reverse osmosis filtration.
  • The ability to bring the values ​​of the parameters of the purified liquid to the values ​​required for plant growth in an artificial reservoir. For this, ready-made kits for the remineralization of osmosis are produced.
  • Obtaining practically distilled water in the required volume due to its gradual selection, storage in a separate container and regular replenishment.
  • Easy replacement of cartridges.
  • Osmotic water treatment helps dissolve sea salt.
  • Possibility of draining unfiltered liquid together with dirt and bacteria into the sewer.

Service

Timely maintenance of the osmotic unit allows you to obtain clean water throughout the entire service life, which is 3 years. Maintenance is reduced to replacing the used elements of the osmotic filter. How often such replacements will be needed depends on the intensity of the use of reverse osmosis and the quality of the water in the water supply system. If you use reverse osmosis when preparing water for an aquarium, the wear of its elements is accelerated.

In this case, the pre-filter cartridges are replaced after 4-6 months, the carbon filter. once a year, and the membrane. once every 2 years. The higher the water hardness, the more often the membrane needs to be replaced. It is quite easy to assess its condition by the quality of the filtered liquid. A worn membrane leaves more minerals. The membrane is the most expensive filter element; periodic flushing allows prolonging its service life.

Principle of operation

The filter used in everyday life works on the principle of reverse osmosis. The device consists of a reverse osmosis membrane and components that ensure its efficient use. A fairly simple principle of operation of an osmotic filter is the passage of a liquid containing some impurities through a fine-pored membrane. During its passage, it is filtered at the molecular level, since even under pressure it is only water molecules that can break through the smallest pores of the membrane. All substances dissolved in it are retained by the membrane. This purification method produces the purest water.

What is osmosis for??

It may seem strange to people who are far from aquarism, why osmosis is needed at all. But those who are at least a little familiar with m and fish farming will understand the answer to this question. osmosis for an aquarium is necessary to reduce water hardness.

The thing is that many types of aquarium fish are quite demanding on water parameters, such as hardness, softness, acidity, etc. But it is especially important to comply with the required parameters for a particular species during the spawning period, without this often even spawning does not occur. And to raise the fry, it is important to maintain the necessary parameters, otherwise it simply will not survive (as an example, red neon)!

Osmosis plant selection

You can decide which osmosis is best for an aquarium based on a number of indicators. First of all, this is the volume of the aquarium. If you have a small artificial reservoir, but it is planned to contain complex fish species, then you will need an osmosis installation. But there is no need to purchase too powerful equipment, because it turns out that the entire power reserve will not be used, and you will pay more than you should!

Well, one more criterion that affects the price of equipment. This is the degree of final water purification. Most of the equipment allows you to get 95% purified water, but there is equipment that can purify water by 99%. It will cost more. And before buying such a system, soberly assess what you need in order not to overpay.

You can create osmosis for an aquarium with your own hands, but this requires technical knowledge and some experience. Yes, and independently created equipment will be significantly inferior to industrial equipment, both in terms of the percentage of water purification and in terms of volume.!

Terms of use

So, we figured out what osmosis is for an aquarium, now it’s worth saying a few words about the rules for its use:

  • The first and most important rule to keep in mind. it is a ban on the use of pure osmosis. This means that you cannot add only purified water to the aquarium, before that it must be mixed partially with the old aquarium. The explanation is simple. there is also no ideal environment in nature, and by placing fish in pure osmosis, you risk killing them.
  • Do not change a large volume of water, because an abrupt change in water parameters can be detrimental to the inhabitants of the aquarium.
  • Well, the third rule says that osmosis for aquarium fish that have been living in an aquarium for many generations can be destructive. The fact is that for many generations the fish have managed to adapt to new water parameters and natural characteristics are no longer important for them.

But still there is a number of fish that will not regularly produce offspring without osmosis, in particular, these are fish of the Cichlid family.

Osmosis and marine aquarium

Perhaps one of the most difficult areas in home aquaristics is the marine aquarium. Creating a piece of the sea at home is only possible for an experienced aquarist, for beginners it is better not even to try to do it.

The whole difficulty lies not in creating the required water parameters, but in constantly maintaining them at the same values. And given the fact that you need to regularly change the water in the aquarium, a failure in the parameters will almost certainly occur. And in such a situation, osmosis for a marine aquarium is a real salvation.

But it is worth remembering that before adding purified water to it, you need to throw all the required additives (sea salt, etc.), and only by comparing the parameters in the new water with the water composition in the aquarium, it can be poured into the aquarium.

Systems should not be confused

When considering water purification, it is important to understand the differences between simple osmosis and reverse osmosis for an aquarium. To make it clearer, let us briefly consider the principle of operation of these two systems. So:

  • Osmosis. To obtain purified water, two communicating vessels are taken, the connection between them is due to a semi-permeable membrane. It resists the flow of water, which will flow from the vessel, in which the resistance is less, to the one where it is greater. This is how the osmosis plant functions.
  • Reverse osmosis. We take the same two vessels communicating with each other, and create an increased pressure in the one where the resistance is higher, then the water begins to flow in the opposite direction. This is the reverse osmosis system.

Osmosis for aquarium: indications and warnings for use

How to understand whether it is worth purchasing an osmosis installation?

You do not always need to purchase any aquarium equipment if you bought an aquarium and got fish. Much depends on how much of the aquarium you have, and most importantly, what kind of fish and for what purpose you plan to keep in it.

So, if you just want to put an aquarium to decorate the interior and keep beautiful, but undemanding fish in it, then you don’t need a reverse osmosis filter for an aquarium. But if you plan not only to keep many species, but also to professionally breed them, then you cannot do without such equipment.

The choice of system depends on the amount of clean water required for the change weekly. For several aquariums with a volume of 400 liters or more, you will have enough equipment that produces 200 liters or more. This is due to the fact that you still will not change a large percentage of the water in the aquarium at once, but will replace it gradually.

What it is?

The procedure for filtering a liquid, when moisture passes through a special diaphragm that traps almost 90% of all unnecessary and harmful impurities, is called reverse osmosis. Only water passes through the membrane, all other impurities are retained on it. It is imperative to take this into account and add all the nutrients and minerals yourself. Various types of reverse osmosis water filtration systems are available on the market. They can be divided into several types, which differ in the following points:

  • filtration level;
  • efficiency factor;
  • aperture option.

The most popular is the filtering system with a composite film membrane. It cleans the liquid in the aquarium very efficiently. Additionally, mechanical and carbon filters help to remove moisture.

Using reverse osmosis

Caring for the aquarium, in addition to aesthetic pleasure, also creates some problems. Aquarium owners know firsthand that each type of fish needs to create ideal living conditions. Including the liquid in the reservoir must be brought to an acceptable state for the comfortable stay of residents in it. Osmosis will help with this, the use of which will bring the aqueous solution to a state close to optimal.

Osmosis water is filtered in both freshwater and saltwater aquariums. In freshwater aquariums, the use of a reverse osmosis filtration system is optional, and there are other cheaper options. But if you breed fish and other creatures that are especially demanding on water hardness, then at least one filter you still need.

For seawater bodies of water that contain particularly capricious fish or coral species, the purchase of reverse osmosis will be a profitable investment. Since the system has a rather high price, it is worth considering whether it is really necessary. Before buying, you should conduct a study of the water you use to fill your aquariums and make a decision based on the results of the tests. Before using the filtration system, you need to remember a few simple rules.

  • A sudden change in water quality for the better can put the inhabitants of the aquarium into a stressful state. It is necessary to take into account the amount of fluid to be replaced.
  • It is forbidden to completely fill the tank with purified water. This liquid lacks useful substances that are required for a comfortable stay of pets in the aquarium.

The living conditions of ornamental fish differ from natural ones. In order for the inhabitants of the home reservoir not to get sick and not die, the peculiarities of keeping fish species should be observed.

Advantages of a reverse osmosis system

The device became widespread due to the following.

  • Environmental friendliness. In the manufacture of products of this type, only proven, environmentally friendly materials are used. Therefore, there is no reason to fear for the health and life of pets.
  • Cleaning. Due to its high performance, the filter copes with moisture contamination, quickly and efficiently removing all additives.
  • Small size. The product has compact dimensions and is available in use.

Osmosis for an aquarium: what it is and how to use it correctly?

Any owner of a home pond knows that the well-being of the aquarium population is highly dependent on the quality of the water. In order to create a favorable habitat in a home reservoir, water purification and circulation systems will be required. Their use will have a positive effect on the lifespan of pets. Consider one of the most advanced. a reverse osmosis system.

Principle of operation

To obtain osmosis water, the filtration system is connected to the water supply network and from it receives liquid for cleaning, and all unnecessary and harmful is sent to the sewer. To protect against failure of the most important element of the product. the membrane, you should pay attention to the pre-cleaning stage. In this process, up to 3 different filters can be used, the purpose of which is to prepare an aqueous solution before the operation of the diaphragm.

Initially, the water is purified by a mechanical filter that removes a variety of substances such as sand, clay and other impurities. Then it is sent to a carbon filter, with its help heavy metals, chlorine and other chemicals are removed. The quality of the carbon filter is of great importance, the main task of which is to purify water from all kinds of chemical compounds.

And at the final stage, moisture enters the fine filter, which cleans it from the smallest mechanical impurities. After performing these procedures, water from the filter enters the diaphragm, which conducts final cleaning. The reverse osmosis process produces the purest, almost distilled liquid that can only be used in limited quantities.

To correct this deficiency, it is necessary to enrich the water with minerals. Remineralization. the procedure for adding mineral additives to water that has passed through reverse osmosis.

This is necessary in order to prevent the processes of wilting of plants in the aquarium and diseases of fish.

All devices require service, including the osmosis filtration system. From time to time, users should monitor the water hardness and the hydrogen concentration level. If the indicators change and cease to suit the owner, then filters and aperture should be replaced.

For information on why you need a reverse osmosis filter for an aquarium, see the next video.

Do-it-yourself osmosis for an aquarium

  • Mechanical and carbon filter.
  • Diaphragm housing.
  • Membrane.
  • Container for fluid passed through the device.
  • Couplings, connecting pipes.
  • Crane.

It is simple to build the device yourself: the membrane is inserted into the housing and connected to the filters using a tube so that water passes first through the filter cartridges, and lastly through the membrane. One of the tubes is connected to the water supply using a coupling and a ball valve. The second two tubes are located at the end of the device: one tube must be fixed in a container designed for purified water. The second tube is connected to the sewage system to drain the liquid: a hole is drilled in the siphon, a gasket is glued and half rings are installed, then a tube is inserted into the hole and the bolts are tightened.

Why do you need osmosis

an artificial reservoir with fish is a responsible business, because silent pets cannot take care of themselves. Every aquarist knows that certain species of fish require individual water conditions and that tap water is difficult to bring to life, so experienced owners use aquarium osmosis systems to help normalize water conditions.

The systems are used for both freshwater and saltwater aquariums. Salty creatures are demanding for phosphates, nitrates and sulfates. Therefore, for capricious pets, artificially prepared liquid is used. the water is prepared using a filter, after which the necessary components are added.

In freshwater tanks, the installation of such a system is necessary to keep shellfish or shrimp, which do not tolerate the accumulation of metals in the liquid. Also, a filter of this type is used to breed Apistogram cichlids. this phenotype requires clean and soft water for reproduction.

Service

Like any device, a reverse osmosis filter for an aquarium needs testing and replacement of broken parts. Periodically, experienced aquarists check the water with tests, determining the level of hardness and pH. If the indicators increase, and the composition of the liquid ceases to suit the owner, the membrane and filter materials should be replaced.

Installation of reverse osmosis for an aquarium

The owners of artificial reservoirs with fish realize that the life expectancy and condition of pets depend on the parameters of the water in the tank, therefore they use osmosis for the aquarium. a special water purification filter. Thanks to the operation of this device, hazardous substances are removed from the water in the aquarium, and the liquid becomes purest. Before installing the filter in your own reservoir, you should know the principle of reverse osmosis and, of course, what is osmosis.

Benefits of osmosis

The popularity of the device is due to the following factors:

  • Cleanliness. in the manufacture of filters of this kind, ecological materials are used, so there is no need to worry about the health of the flora and fauna in the aquarium. In addition, it is much more pleasant to keep fish and plants in a clean tank.
  • Cleaning quality. the filter copes with cleaning quickly and efficiently, removing organic compounds, life-threatening impurities, and chemical constituents.
  • Compactness. the device is small and easy to use. Filtration is performed by owners in several stages.

What is osmosis?

Reverse osmosis in an aquarium is a process during which liquid passes through a special membrane and is purified from salts, dirt and other elements. In other words, after the operation of the reverse osmosis filter, 90% of the minerals are removed from the liquid.

  • The degree of purification of the liquid.
  • Productivity.
  • A kind of membrane.

The most popular is a filter with a membrane in the form of a composite film, which is characterized by an effective degree of water purification. In addition, a mechanical and carbon filter is additionally introduced into the reverse osmosis filter.

An interesting fact: scientists first learned about the existence of this type of cleaning thanks to seagulls. Noticing that these birds use salt water harmlessly, the scientists found out that a membrane is located in the beak of the seagulls, which converts the salt liquid into fresh.

Features of use

Having assembled the water purification system yourself, before using the device, you must take into account several nuances:

A reverse osmosis filter for water purification will help completely neutralize hazardous impurities and substances in tap water, making it suitable for keeping fish. In order to avoid negative consequences when using the device, you must heed the advice of experts and adhere to the rules of use.
