Video: Why Does The Water In The Aquarium Become Cloudy?
Cloudy water in an aquarium can occur for a variety of reasons; dealing with these phenomena is not always easy. In the most harmless case, the water becomes cloudy due to small particles of soil suspended in it, for example, after careless pouring of water into an aquarium. Such turbidity does not have any unpleasant consequences and after a while it disappears by itself when the turbidity settles to the bottom.
The water in the aquarium becomes cloudy from the appearance in it of a large number of putrefactive bacteria, which are very harmful not only for fish, but also for aquatic plants. The reason for the appearance of such bacteria is improper feeding and overly dense planting of fish in the aquarium. For good water filtration, coarse-grained, cleanly washed river sand, preferably dark in color, with a layer of 4-5 cm, should be poured onto the bottom of the aquarium. water at the same temperature. A properly equipped and well maintained aquarium can last for years without changing the water. The so-called biological balance is established in it. The fish stocking rate is 2-3 pieces of 3-5 cm in size for 1-3 liters of water.

The main troubles arise from improper feeding. First of all, dry food should be abandoned: fish eat dry food rather poorly, and water deteriorates very quickly from it. If you have to resort to dry food, then it should be given a little and make sure that all the food is eaten immediately. Snails, willingly eating the remains of food, are of great help here. A properly formulated diet must necessarily include live food. One of the best food is bloodworms. It should be given based on the norm of 3-5 worms per day for each small adult fish.
It is necessary to ensure that any food is eaten in 10-15 minutes: constant presence of food at the bottom of the aquarium is unacceptable. Tubule worms are also good food, but they should be rinsed very thoroughly in clean water to remove dirt before feeding them to the fish. A transparent floating larva of one of the mosquito species serves as an excellent food. It does not bury itself in the ground, lives in an aquarium for a long time and is very eagerly eaten by fish. At home, enchitrea worms are easily bred in a small box with earth. Daphnia and Cyclops are good food, which you can catch yourself in some puddle with a net made of dense nylon.
With some experience and skill, you can feed the fish with scraped raw meat, but this should be done with the greatest care: the water from the meat spoils very quickly. If the water has become cloudy, then you need to stop feeding for a few days: the bacteria will die, and this will not harm the fish. And there is one more rule: it is better to underfeed than overfeed. If these conditions are met, the water in the aquarium will be clear.
Many novice aquarists, when cleaning a small aquarium, completely replace the water in it, replanting fish and taking out plants. In this case, fish are injured and plants deteriorate. You can often hear a statement full of upset: "The more often I change the water, the more it becomes cloudy." This is true.
In a newly equipped aquarium, the water can be cloudy for the first few days due to the strong multiplication of unicellular organisms. After the aquarium is prepared and filled with water, you should be patient and not rush to stock it. As a rule, on the second or third day, the water in the aquarium becomes cloudy, as if a few drops of milk had dripped into it, because after a complete replacement of the water, after a while microorganisms introduced into the aquarium with fish and plants usually develop rapidly, and the water does not become cloudy. from weed particles, and from ciliates, the so-called "ciliates" appears.
The rapid growth of bacteria can manifest itself in your aquarium every time you change a large amount of water, as well as in those cases when you forget to remove from the aquarium the remnants of uneaten food (especially dry), rotting plants in time. Such turbidity, if you eliminate its cause and wait for a while, passes.
In an aquarium, interconnected biological and chemical processes are constantly taking place, as a result of which some animals and plant organisms are born, others die.
A huge mass of bacteria living in the water column and in the soil processes the decay products and vital activity of plants, food residues, and fish excrement. Bacteria, in turn, are food for ciliates, etc.
If you do not change the water to a new one, as many inexperienced aquarists do, fearing cloudiness, then in a week or two the bacterial cloudiness disappears and the water becomes crystal clear. You can speed up this process by adding a small amount of water from the old one to the water of the new aquarium.
Overcrowded aquariums can become cloudy, especially if there are few plants and the water is not ventilated or filtered. In such an aquarium, the accumulating metabolic products serve as a good breeding ground for the mass reproduction of bacteria and unicellular organisms. In this case, you need to quickly plant the excess fish. If the situation is not corrected in time, this can lead to disease and even mass death of fish, not to mention the fact that such an aquarium looks ugly.

Fish digging in the ground can also cause cloudy water. This cloudiness is harmless and can be easily eliminated by adding a layer of top layer of cleanly washed sand to the bottom of the tank.
* A complete change of water in the aquarium should not be carried out.
* It is necessary to ensure that any food is eaten within 10-15 minutes: constant presence of food at the bottom of the aquarium is unacceptable!
* In a newly equipped aquarium, the water can be cloudy for the first few days due to the strong multiplication of single-celled organisms.
* An overcrowded aquarium can become cloudy, especially if there are few plants and the water is not ventilated or filtered.
