The main problem is that most aquarium fish feel well only in soft water. If taken for aquarium soil contains soluble salts of calcium, they will gradually move into the water and increase its rigidity, which will impact negatively on the inhabitants of the aquarium.
Therefore, the algorithm to find beautiful soil, washed, pour into the aquarium" is incorrect. Beautiful is not good, so the aquarium can't use coral sand, small rock, marble crumb, no matter how beautiful they look.
For aquarium will not fit and fine sand with grains of diameter smaller than 1 mm. Such a soil will be too dense, almost impermeable to water, it will begin the process of decay. In this soile bad feel of the plant, their leaves will be small and faded.
Alternatively, in the case of using fine sand in the aquarium, it is necessary to arrange the second plastic bottom with nasverlennye in it small holes. The distance between the bottom of the aquarium and the second bottom is 1-2 cm On the second floor in two layers is placed a fine mesh (not metal!), she poured the sand. From the space under the second bottom pump pumped out the water, thereby ensuring the forced circulation through the soil. Such second bottom is useful for any aquarium.
Best choice for aquarium soiland is small, with a diameter from 1 to 5 mm, gravel of quartz or feldspar. Pour it into a bowl, cover with water, drain the supernatant waste. Then rinse, actively stirring, until, until the water will not stay perfectly clean.
In that case, if there is a suspected high content of calcium, the soil must be treated with hydrochloric acid Bay for a couple of hours in a plastic basin. Then it should be no less than half an hour wash with running water to remove all traces of acid. To test whether the soile, calcium, splash him with hydrochloric acid or vinegar. If bubbles appear, the soil needs treatment with acid.
Aquarium ground, thus prepared, will not saturate the water with calcium salts, therefore, its stiffness will be a long time to stay at an optimal level. Sometimes novice aquarists only add water to replace evaporated is wrong, since it leads to a gradual increase in the level of rigidity. It is recommended not to top up weekly, but change is not less than 1/5 of the volume in the tank water.
Advice 2: How to prepare the soil for aquarium
Aquariums - a very popular hobby. Its essence lies in the fact that in an enclosed artificial pond to simulate ekosistemu. Using their knowledge and capabilities, the aquarist creates a wonderful world. Despite the variety of aquariums, they are organized on the same principle: first put the soil, then planted the algae and after the run of fish. Therefore, the first thing after you have purchased your aquarium, do some preparation of the soil.
The main function of the soiland it is a substrate for strengthening the plants. Some aquarists, to facilitate easy cleaning of the aquarium, do not use sand or pebbles, but if you want that the aquarium performed a decorative function, the ground it is better to use. There are living organisms that decompose dead organic matter into useful substances and cleansing the aquarium. In addition, in the soile stored reserves of carbon dioxide that affect the buffering of the water.
When selecting the groundand notice that it shall not release into water soluble substances, must not be sharp edges, so as not to hurt the fish and should be permeable to water. Usually, as the soiland use river sand or pebbles. To make sure that the soil is suitable for you, it is quite a splash of vinegar. If after that, on the surface no blisters or foam, so this primer can be used.
If you decide not to buy soil at the store and prepare it yourself, go to the nearest Creek or river for large river sand. Be sure to clean the soil from contaminants – sticks, particles, algae, pieces of paper.
Take a sieve and sift the sand through it. Everything that takes place in sieve, throw away ruthlessly, still in use in the aquarium it will only pollute the water. Repeat the procedure several times, then proceed to flushing the soil.
Thoroughly rinse the soil under warm running water, constantly stirring it. It is necessary that the soil is completely free from fine particles. The better you rinse the sand the faster the water in the aquarium will become transparent and you will be able to settle there fish.
If desired, soil can be decontaminated. To do this, rinse it with a weak solution of potassium permanganate, then do not forget to rinse the sand in tap water.
Now the ground can be used in the aquarium. Place an even layer 4-7 centimeters and begin to create their underwater Kingdom.
