To answer the question why the water in the aquarium becomes cloudy, it is necessary to analyze all sorts of reasons for its pollution. One of the main causes of turbidity is excessive feed. If the water in the aquarium becomes cloudy, try to limit the amount of food and feed the fish once a day. They must eat all the food in 15 minutes. If during this time they have not eaten everything, reduce the portion. Arrange your fish fasting day once a week.
Another most common reason that answers the question why the aquarium has muddy water is the lack of a filter or its insufficient power. The filter should match the volume of water in your tank.
It is sometimes impossible to immediately establish why the water in the aquarium becomes cloudy, in which case a third of the water should be replaced. If this does not help, you may have to replace all the water in the aquarium. Experienced aquarists advise changing the water completely at such times:
- Aquarium up to 100 l - once a year;
- Aquarium 100-200 l - once every 3 years;
- Aquarium over 200 l - once every 5 years.
Sometimes it is difficult to determine why the water in the aquarium becomes cloudy, because clouding is the result of careless pouring of water or the actions of fish actively digging the ground. In this case, the smallest particles of soil and algae float in the water.
Clouding of the water can be caused by the death of one or more fish, so check the number of fish every day and immediately remove the dead.
Turbidity of the water caused by the active growth in the number of bacteria in the water is very dangerous. This phenomenon often occurs in a highly crowded aquarium with a small number of living plants. In such aquariums, the waste products of all its inhabitants accumulate, which represent an excellent breeding ground for many putrefactive bacteria. Such bacteria are harmful to fish and plants. In this case, it is necessary to put the extra fish into another container and do not feed them at all for 2-3 days. During this time, the bacteria must die. In such cases, special preparations are often used that are added to water to kill bacteria. In severe situations, it becomes necessary to completely replace the water. Activated carbon, which absorbs various harmful substances, must be placed in the filter. The main criterion for water quality is its smell. Of aquatic plants, the toothed elodea is most effective against turbidity.
For the purification of water, medications, for example, such as bicilin-5, can also be used. It must be added to water at the rate of 5000 PIECES per liter. This treatment is carried out for 3 days. A drug solution is prepared daily before water treatment. Biological clouding is often removed using ozone or ultraviolet sterilization. If no means help, you will have to replace not only water, but also the soil.
Misuse of a variety of chemicals causes a change in pH. The consequence of this is the clouding of the water and the appearance of a whitish coating on the decor, stones and plants. Very often this happens when using chemicals in their pure form, that is, without their preliminary dissolution. In this case, it is better to put all the fish in another aquarium.
Sometimes clouding of water is caused by the use of wooden decor elements and water filtration using peat. Before placing in the aquarium driftwood must be thoroughly soaked. In this case, activated carbon is used to purify water.
When you understand why the water in the aquarium becomes cloudy, immediately begin to take measures to clean it, because poor-quality water can destroy all your fish. If you have taken care of living beings, you should be extremely careful.
