Requirements for the acidity of water

The requirements for the acidity of the water are due to the creation of a favorable habitat for fish. Distilled water is the basis for measuring the acidity of water (pH). In it, the amount of ionic acids and ionic bases is equal, the pH is 7, and therefore it is considered neutral. If the pH is above 7, then such water is alkaline, below it is acidic.

Since, basically, water from a home tap is used to fill the aquarium, first you need to test it for hardness and acidity. Thus, it is possible to determine how suitable the water is for the desired types of fish, or how much effort and costs will be required to ensure the necessary conditions.

The choice of certain types of fish affects the ability to maintain the required water temperature in the aquarium. So, cold-water fish require a water temperature of 14 °.20 ° С, warm-water ones. above 18 °.20 ° С, some tropical ones from 25 ° С.

## Aquarium inhabitants

To populate an aquarium, it is required to take into account the compatibility of fish species in many ways. For the inexperienced aquarist, it is better to start with the popular dozen of fish that meet the principles of compatibility.

## Populating an aquarium of 100 liters

On the forums, the question is often “who to populate an aquarium of 100 liters?”. The answers are different and depend on the respondent’s own experience. Since the Blue Barbus company has been professionally engaged in the aquarium business for more than one year, its specialists provide advice on aquariums, we will not stand aside and tell you about populating an aquarium with a volume of 100 liters. Regarding the aquarium itself. such a volume allows you to create a stable ecosystem, which is not so easy to disrupt by your inept actions, it is compact, it is easy to find the necessary equipment for it, and it is easy to care for.

So, if an aquarium for 100 liters is purchased, it is necessary to take into account some requirements, the observance of which ensures the successful launch of the aquarium, its settlement and its vital activity.

## Habitat

The type of aquarium is determined by the chemical properties and the temperature of the water. Depending on these indicators, the aquarium is freshwater, marine, brackish water, cold water, warm water. brackish and saltwater aquariums require some experience or the services of a specialist aquarium company such as Blue Barbus. The freshwater aquarium, which we will talk about, is the most common type among novice aquarists due to its ease of maintenance and a wide selection of freshwater fish and plants.

Physicochemical properties must be taken into account when selecting fish. There are a number of basic indicators of water, however, the most important are hardness and acidity.

The total hardness of water (GH) is determined by the amount of calcium (Ca) and magnesium (Mg) salts dissolved in it. The unit of measurement is the German degree of hardness (dH). She plays a significant role in the passage of biological processes. In international aquaristics, there is the following gradation of water depending on the indicators, where 1 ° is equal to 1 dH:

- 0 °. 4 °. very soft water;
- 5 °. 8 °. soft water;
- 9 °. 12 °. medium hard water;
- 13 °. 18 °. hardish water;
- 19 °. 30 °. hard water;
- From 30 °. very hard water.

Magnesium or calcium combines with carbon dioxide to form salts. They are characterized by carbonate hardness (KH). Carbonates serve as a buffer for acidity to prevent strong surges. In a freshwater aquarium, the carbonate hardness should not fall below 3 ° dH. You can adjust the stiffness indicators using special preparations, type of soil.

### Guppy

For all strata of living, the guppy is ideal. a representative of viviparous. For novice aquarists, it is better to keep the classic, rather than capricious pedigree, guppy species. In a general aquarium, do not populate with predatory and aggressive fish.

Good for a species aquarium. This is a peaceful, cheerful and lively fish. Males fight for the female. They have a variety of color variations. Size up to 6 cm. Endler’s Guppy, a kind of guppy, is smaller than its counterparts. The optimum temperature is 20 °.26 ° C. They need live plants, bright lighting and free swimming space. In the thickets of plants, the female hides from the annoying male. The fish are jumping, so a cover is **needed** on the aquarium. Omnivorous, like mosquito larvae. The feed should be small so as not to choke. You can’t overfeed. Not all fish are served overexposed.

Top ten popular fish for novice aquarists include zebrafish, cardinals, blue neons, thorns, pristella, hasmania, macropods, wedge-spotted rasbora, acanthophthalmus loach.

- The environment is unpretentious and hardy enough with changes in water properties. Withstand significant drops for a short time.

When selecting fish, it is necessary to be guided by the similarity of the natural parameters of the environment, where they come from, and the parameters of your water obtained when testing. Warm-water and cold-water fish cannot be lodged together.

Critical changes in water parameters are 3 ° С. for temperature, 5 °. for hardness, 0.5 units. for acidity.

By their temperament, they settle in different layers of the water, depending on their territorial residence. Schooling fish are mobile and impetuous. Pisces leading a paired or harem lifestyle are more measured and phlegmatic. Lively fish can drive their calm neighbors into vegetation and keep them under siege. Badass will not be able to swim past the fluttering veil fins. Nimble, eat food faster and leave unhurried fish hungry.

Comparability of size is important so that a small fish does not have the opportunity to be eaten by a large one. Even if a large fish has a peaceful character, then the small one will hide due to stress and lose its bright color.

The stocking density of fish depends on the size and temperament of the fish, the power of aeration and the quality of filtration. The selection takes into account the adult size of the fish. There is no universal calculation, but for an approximate 100 liter aquarium, 1 liter per 1 cm of fish length can be considered. If the length of the fish is over 6 cm, you need to add another 1-2 liters of water. It is important that there is no overpopulation by strata of residence.

- Social. compatible when divided into layers

Schooling fish species, the number of which in a school is preferably at least 4 individuals, are well compatible with all species. Fish. loners do not get along with their species, since the dominant individual will beat its congeners. Paired fish during the mating season become aggressive and for other species it is necessary to create shelters in the aquarium or transplant them separately.

### Somik ancistrus

A popular species of lorikarievs. Territorial fish, it is not advisable to keep more than two males, they fight. Size up to 12-15 cm. Leads a twilight lifestyle.

The optimal tropical temperature is 22 °.25 ° C. Loves clean water enriched with oxygen. Keeps in streams of intense aeration. Numerous shelters, driftwood or thickets of plants are **needed** to be able to rest or hide from annoying neighbors. It feeds on fouling from surfaces and food residues from other aquarium inhabitants. If hungry, it can scrape and spoil plants. When keeping a group of ancistrus, additional feeding is necessary for herbivorous fish. Popular for his sucker-mouth cleaning abilities.

It is possible to settle one or both types of barbs in the middle-lower layer:

### Pearl gourami

The fish is similar in characteristics to marble gourami, however, it is more thermophilic. Prefers bright, indirect, light. Air on the surface of the water must be well ventilated and warm so that fish do not catch cold. Therefore, an aquarium cover is **needed**.

### Final calculation formula

The final formula for calculating the amount of **soil**: m = 1000r n V: С

Length is measured in cm (centimeters), weight. in kg (kilogram)

Where:

- m is the mass of the soil;
- p is the specific density in kg / cm3;
- V is the volume;
- C. the height of the aquarium;
- n. ground height.

We take the data on the density of the soil from the table, measure the height of the aquarium with a ruler or tape measure.

## How to calculate the amount of soil?

Sand, pebbles, small stones or granite are chosen as bottom coverings. Bulk materials, due to differences in molecular structure, differ in density.

The same volume of sand or granite has a different weight. The problem arises, how many pebbles or small pebbles to prepare to create a given thickness of the aquarium soil.

To calculate the required amount of soil, you will have to remember physics and geometry for grade 4.5:

- V. volume, in liters.
- A. length, dm.
- B. width, dm.
- С. height, dm.

Liters are best converted to cm3.

- 1 dm = 10 cm.
- 1 dm3 = 1 liter of water.
- 1 liter of water = 1000 cm3 of water.

For example, an aquarium with a volume of 100 liters will contain 100 dm3 of water, or 1,000,000 cm3 of water.

The mass of the soil is calculated by the formula: m = p V, where:

- Weight, kg.
- Density, kg / cm3.
- Volume cm3.

Reference data for the main types of materials used as a substrate for an aquarium are given in the table at the end of the article.

*Soil* of different fractions is usually combined, for example, 2 cm of sand and 2 cm of pebbles. Therefore, we derive the weight formula for a height of 1 cm of filled soil, and the total soil height can be easily calculated by adding.

The volume of *soil* is 1 cm of height: V = A B 1 cm (or in liters V = A B 1 cm: 1000);

Therefore, the mass of 1 cm of **soil** over the entire area of the bottom of the aquarium: m = p V = p A B 1 cm, where:

- Mass. in kilograms.
- A, B and C. in centimeters.
- p. kg / cm3.

For a soil thickness of several cm (n), the formula will take the form: m = p V = p A B n

If we know the volume of the aquarium in liters, substitute V:

m = p V: C n, we convert the volume from liters to cubic centimeters: m = p V: C n 1000

Where:

- m is the mass of soil in kilograms;
- p is the specific density in kg / cm 3;
- V. volume, cm 3;
- C. the height of the aquarium, cm;
- n. ground height, cm.

### For 120

Aquarium height. C = 60.

We calculate the weight of large pebbles for a layer of 6 cm:

(the density value of large pebbles from the table is 0.0014 kg / cm3)

m = 1000 0.0014 6 120: 60 = 16.8 kg.

### For 100

It is necessary to calculate the weight of fine sand for a layer of 2 cm.

The height of the aquarium. C = 47;

(the density value of fine sand from the table is 0.0017 kg / cm3)

m = 1000 0.0017 2 100: 47 = 7.2 kg.

## Density table

Specific gravity indicators in kg / cm3:

small | middle | large | |

The size | 1. 3 mm | 3. 5 mm | 5. 15 mm |

Sand | 0.0017 | 0.00165 | – |

Small pebbles | 0.0017 | 0.0016 | 0.0014 |

Pebbles | 0.00165 | 0.0016 | 0.0014 |

Granite | 0.0016 | 0.00145 | 0.0013 |

In some cases, these density values may slightly differ from real physical values due to humidity and average statistical spread.

## How much sand is *needed*?

### For 50

Aquarium height. С = 40.

We calculate the weight of small granite chips for a layer of 2 cm:

(the density value of fine granite chips from the table is 0.0017 kg / cm3)

m = 1000 0.0016 2 50: 40 = 4 kg.

### For 120

Aquarium height. C = 60.

We calculate the weight of large pebbles for a layer of 6 cm:

(the density value of large pebbles from the table is 0.0014 kg / cm3)

m = 1000 0.0014 6 120: 60 = 16.8 kg.

The formula for calculating the amount of **soil** in and the reference data of the table allow with sufficient accuracy to determine the weight of a given thickness of the bulk material of the aquarium independently, without resorting to outside help, saving time and money.

### For 200

Aquarium height. C = 90

We calculate the weight of large granite stones for a layer of 8 cm:

(the density value of large granite stones is 0.0013 kg / cm3)

m = 1000 0.0013 8 200: 90 = 23 kg.

## How much soil is **needed** in a 100 liter aquarium

In the aquarium biosystem, the *soil* plays a significant role. The choice of grain size and the amount of bulk material determines the type of aquarium, the health and life of the populations inhabiting it.

The bottom cover serves as a substrate for plant roots, a place for their reproduction and nutrition. Lack of floor covering for pets in a confined living space creates discomfort and leads to stress.

## Required layer height

The height of the soil layer in the aquarium can vary from 2 to 10 cm. With a small number of plants, a minimum 2 cm bottom cover is sufficient. When simulating natural sea or river relief, creating a landscape of coral reefs, the thickness of the soil reaches 5-10 cm, in addition to the aesthetic function, maintaining the ecological balance of the enclosed volume.

If it is too thick, the soil can cause acidification of the water. Excessive *soil* materials are harmful to the aquarium, as well as lack or lack of it.

### For a 30 liter container

It is necessary to calculate the weight of the average sand for a layer of 3 cm:

The height of the aquarium. C = 30;

(the density value of average sand from the table is 0.00165 kg / cm3)

m = 1000 0.00165 2 30: 30 = 3 kg.

### For 100

It is necessary to calculate the weight of fine sand for a layer of 2 cm.

The height of the aquarium. C = 47;

(the density value of fine sand from the table is 0.0017 kg / cm3)

m = 1000 0.0017 2 100: 47 = 7.2 kg.

### Final calculation formula

The final formula for calculating the amount of soil: m = 1000r n V: С

Length is measured in cm (centimeters), weight. in kg (kilogram)

Where:

- m is the mass of the soil;
- p is the specific density in kg / cm3;
- V is the volume;
- C. the height of the aquarium;
- n. ground height.

We take the data on the density of the soil from the table, measure the height of the aquarium with a ruler or tape measure.

## Factors influencing the choice of the number of fish

The physicochemical characteristics of water is one of the key issues in organizing proper housing. It takes into account the percentage of nitrogen, its compounds, the level of acidity, saturation of O2, as well as temperature.

oxygen priority. It is provided by planting algae, as well as through the use of additional technical means that generate this gas.

The second factor combined such indicators as the number of individuals, their size, age, weight, feeding activity and growth rate.

The more food the fish eats, the more food remains will settle to the bottom of the aquarium. Decaying food releases toxic ammonia, which negatively affects the health of underwater inhabitants.

- the presence of soil, its quantity, quality and composition;
- the presence of algae and their varieties;
- filtration equipment; frequency and amount of feed dispensed.

Keep all of these aspects in mind when planning your pet water space.

## How many fish to keep in the aquarium

To calculate how many fish can be kept in an aquarium at the same time, there are some important points to keep in mind. In nature, there are a variety of underwater inhabitants, which differ in size, shape, behavior and way of life. Therefore, depending on what kind of fish you settle in your own reservoir, the volume of the container for the dwelling is determined. This article will help you understand the arithmetic when counting pets, as well as the nuances of launching fish into a new habitat.

## Overpopulation signs

The fact that the aquarium is full and it is time to replace it, you will understand by the changes in the behavior and condition of the pets:

- Fish often swim to the surface and gasp for air. This indicates a lack of oxygen for all residents.
- Your pets have lost their rich color and turned pale.
- The fish are stunted. Tightness is often one of the main causes of this phenomenon.
- Your aquarium inhabitants do not breed. In order to acquire offspring, creatures need enough space. If it is not there, you should not expect an increase in the fish family.

If it is currently impossible to acquire a new large aquarium, use other methods of helping your pets. For example, algae or a special generating unit will provide additional oxygen. Lowering the temperature within the acceptable range for the species, will give more comfort.

## Bottom and labyrinth fish

The category of bottom fish includes catfish and bots (suckers and burrowing). They spend their whole life being at the bottom, buried in a layer of aquarium soil. When calculating the number of inhabitants, the size of the creatures is taken into account. The latter plays an important role. For example, 1 ancistrus needs 50 liters, and a plecostomus already requires a 200-liter aquarium.

Labyrinth fish are unique because they are an exception to the general rule. There are about 20 decorative species of these creatures. They owe their name to a special organ, which is called the “labyrinth”.

Thanks to him, the labyrinth species is not affected by oxygen in the water. They can capture it from the air. Therefore, one cockerel will perfectly fit even in a glass, and for two gourami, 20 liters will be enough.

## Fish species and displacement

The recommendations below will help you determine how much water you need for your home. Here are the specific numbers based on the size of the pets and the fluid they need.

Settle small creatures up to 4 cm (cardinals, neons, rasboros and guppies) in small aquariums from 10 to 30 liters. Individuals up to 6 cm long (small species of barbs, guppies, tetras, platies) prefer living space with a volume of 25 liters or more. Calculation. 2.5 liters per individual. These are aquariums of 50, 60 and 100 l.

Pets 10 cm in size are peaceful and calm. Among them are black and cross species of barbs, swordsman and congo. They need a capacity of 100-150 liters.

Fish with a body of 20-30 cm (groups of cichlazes, iris green or blue, zebrafish, gourami, groups of discus, akhara, selective species of goldfish) require volumes from 100 to 500 liters. For example, for two scalars or 4 goldfish, a reservoir of 100 liters is suitable. And even 60 pets of these species peacefully coexist in the 500-liter one. If the volume of the aquarium is minimal, it is comfortable for two to five individuals and no more.

## Optimal tank filling techniques

In the aquarium hobby, there are several options for determining the optimal filling of the reservoir. The simplest, but also the most controversial, is called the rule “3.5 cm per 5 liters of water”, where 3.5 cm is the total length of all fish. There are pitfalls here:

### How much gravel/sand to use in an aquarium

- You need to know in advance the final dimensions of an adult.
- Consider the size and shape of the fish. Large fat inhabitants produce noticeably more waste, which means that they need more water than elongated and slender ones.
- It is only necessary to take into account the real volume of water, minus the occupied soil, plants and other accessories, and this is minus about 15 percent.

The next method is based on the determination of the surface area of the water. (To find out, you need to multiply the width and length of the aquarium.) The larger it is, the more intense the oxygen exchange and the more fish that can be put into the container. For large fish, the optimal ratio is 3 cm of body per 150 cm² of surface, for elongated fish. at 90 cm².

## A few more important requirements

- Use the rule “1 cm per 1 liter” only for small, thin, non-aggressive and unpretentious fish.
- The greater the length and height of the fish’s body, the more water it needs. For example, a 20cm discus requires at least 40 liters of water.
- Fat and slimy fish need more water. For example, a 25 cm goldfish needs at least 30 liters.
- Small aquariums are only suitable for small fish.
- The more aggressive the fish, the more volume it needs.
- Schooling fish are best kept in large aquariums.
- fish can live in a densely planted aquarium with good filtration.
- The inhabitants should be selected so as to evenly populate all layers. You can find out “who is who” according to a simplified scheme: the mouth is turned upwards. the upper layer, directed along the middle line. the middle layer, looks down. the bottom view.

## How many fish can you keep in an aquarium

Knowing the correct answer to this question is just as important as knowing how to care and create optimal conditions for your underwater pets. On the one hand, everyone would like to fill their aquarium with a variety of fish as much as possible, on the other hand, overpopulation should not be allowed, which is fraught not only with limiting the space for swimming, but also with diseases and death of the inhabitants. In this article we will try to figure out how to find a reasonable compromise and not “overload” your aquarium.

## How not to do it

Very often there is advice to choose the number of fish, starting from the volume or the number of liters of container in which they will live. The following is usually taken as an axiom: 5 liters of water is optimal for one fish. Accordingly, 20 fish can be planted in a 100-liter aquarium, etc.

Or even more interesting: for 1 liter of water there should be 1 cm of fish length. A speculative experiment was conducted by one of the professional aquarists, which completely refuted the correctness of this formula. He mentally took a 100-liter classic aquarium and began to “try on” different fish to it.

- First, neon (3 cm). it turned out that 33 pieces would be too few, they would have to look for them with a glance in such a volume.

- Then there was the goldfish (10 cm). From ten individuals of this breed there will be so much waste that it will be necessary to “shovel” them, and even powerful filters will be difficult to cope with this problem.

- Next came the astronotus (25 cm). According to the formula, we can contain four giants in 100 liters, but in real life it is impossible to grow even two in such conditions.

- And finally, there was a protopterus (1 m). You can, of course, try to “shove” it into a vessel of a given volume, but will such an existence be comfortable? Unlikely.

And from them, unfortunately, you do not know that schooling fish can be populated in more compact groups, that “loners” need space, and fighting breeds are better kept separately. They do not say anything about the overconsolidation of a particular layer of water, but each fish prefers its own layer of water (upper, middle or lower). And about many other things. What needs to be considered in order to make the correct calculations?

## Factors that determine the number of fish in an aquarium

The most important limiting factor in water is oxygen. Plants and technical means (as additional sources of this gas) allow to increase the fish stocking density.

Determining its limit is simple: if the fish try to spend most of their time at the surface, convulsively swallowing air (with high-quality aeration!), Then you have overpopulation.

At the same time, you need to check the temperature of the water, since when it rises, oxygen in water dissolves worse.

- The next factor is the number, size, weight, age, food activity and growth rate of the fish.

The larger the individual, the more secretions from it. They, as well as food residues, decompose and release toxic ammonia. If there are too many fish, then it simply will not have time to process and will poison the aquarium. The permissible number of fish can be determined by conducting a chemical analysis of water for nitrogen, ammonia, ammonium, nitrites, nitrates with the help of good tests and analyzing the results.

- It is important whether there is soil in the aquarium, what quality it is and in what quantity.
- Are there living plants and what kind of them are they?
- Is the filtering equipment used and what kind; how often the aquarium is maintained (water changes,
**soil**cleaned, etc.). - How often and in what quantities is the food given, what quality and chemical composition it is, what percentage of the fish are eaten. There are other, but not so important factors.

## Specific fish. specific liters

Some practitioner authors share their experiences and tell which species, in what quantities and aquariums feel great (subject to normal filtration and regular maintenance). Here are some of these tips:

- Small fish (up to 4 cm: neon, cardinal, rassbora, guppy) can be kept in aquariums from 10 liters with a stocking density of 1 liter per 1 fish.
- Small (up to 6 cm: pecilia, thornsia, hasemania, rhodostomus, minor, barbus, guppy) in 20-liter with a stocking density of 1.5 liters per 1 fish.
- Small peaceful (up to 10 cm: swordsman, mollies, congo barbs, cross and black, apistogram) in aquariums of at least 150 liters. Density 3-10 liters per 1 fish. over, for flock water, less is
*needed*, and for individuals. from 5 liters per piece. - Medium peaceful (up to 20 cm: scalar, golden, gourami, zebrafish) in an aquarium from 200 liters. It’s hard to name the rules, there are many exceptions. It all depends on the fish, its mass, behavior, habits. The larger the volume, the more the planting density can be increased.
- Small cichlids up to 10 cm need 40 liters for a pair.
- Malawian cichlids: an aquarium from 150 liters, where no more than 10 liters per fish. Such overpopulation is even necessary, it reduces their aggression.
- Large fish (up to 30 cm: acara, astronotus, cichlazoma) are placed in a pair of 250 liters or ten in 500 liters.
- Discus need an aquarium of 200 liters or more and at least 50 liters per fish.
- Very large (arowana, snakeheads, clary catfish) are best populated in aquariums of at least 1.5 m in length. For 500 l 1-2 fish.
- Catfish and Botsy. They are bottom, they can be ignored in the total amount. The larger the aquarium, the larger the species can be planted. “Suction cup” one, “digging” no more than 5.
- Labyrinth. 10 liters will be enough for one cockerel. Gourami. 20 liters per steam.

What conclusion can be drawn from all this? And such that you need to listen to the recommendations, but not blindly follow the rules, especially the outdated ones. Each aquarium is unique and the approach to each needs an individual one. We hope that our information will help you answer the question of how many fish can be kept in an aquarium.

## How many fish can you settle, keep, plant in an aquarium 100 liters

How many fish can you settle, keep, plant in an aquarium? For example, in an aquarium of 100 liters? Why a hundred? If we take a one-liter aquarium as a calculation, then it will be much easier for us to calculate how many fish can be kept or planted in a larger or smaller aquarium.

In reality, such exact calculations do not exist. There are different ways to determine how many fish you can put in an aquarium. They can be found on the net. In my article, I will publish a list and the option that I use. Let’s see the list. The information is averaged and it is better to plant fewer fish than to overdo it, otherwise you will have to give your pets into good hands or start another aquarium for them. And for the aquarist, aquariums often breed like fry in viviparous fish. It may be impossible to sell the fish or return it to the seller.

A list of the number of fish that can be settled, kept, planted in an aquarium of 100 liters:

This is not a complete list, but you can stick to it.

## A way to determine how many fish you can put in an aquarium

It is not difficult to determine the number of fish from the list, but if you are in doubt, then try this method.

We populate 15 male guppy endlers in a 20 liter aquarium. Pour settled water. We install a small filter and aeration. The next day we check the condition of the water. Nitrite (NO2) tests will be required. We do the test every other day. If the indicator shows at least the lowest value on the scale, then you are overpopulated. If the drip test does not detect nitrite, then we check again the next day. So we monitor the water for a week. Water changes are most often done once a week. If nitrite is not found in the water within a week, then the number of fish for a given volume is quite normal. Using my aquarium example, I found that with 15 small male guppy endlers, the water in a 20 liter aquarium has to be changed 50 percent every other day! If this is a jig, like mine, then that’s okay. And if this is a decorative aquarium with fish for the soul, then it is imperative to reduce the number of fish. I think 5 of my Endler El Tigr Campom guppy fish for 20 liters is quite the best option. You can follow the link and read what kind of fish it is. Also, when testing water, I use a salt meter (water quality tester TDS meter). Why you can use a TDS meter (saline meter) in aquaristics I will write in another article.

What else determines how many fish can be kept in an aquarium of 100 liters, and any other container? If you read carefully about the nitrate cycle, it will immediately become clear to you what needs to be done:

- Plant fast growing plants (don’t forget about plant light)
- Lay aquarium
**soil**, volcanic lava to support the life of nitrifying bacteria - Install biological filter

If you even throw hornwort in the aquarium and put a couple of volcanic lava chunks, you will immediately notice that a water change can be done a day later. Provided that the plants will grow actively. To make fewer substitutions, I put lava, and from the aquarium plants, Anubias barteri nano, a fern of bolbitis gedeloti, I threw a little motogross cirrus and a common hornwort on the surface. For two days now and the water is clear. Nitrite indicator transparent.
