The foam in the fish tank water indicates that the water body is too fat. This is the gas produced after the decomposition of the organic matter in the water, which usually does not disperse for a long time.In view of this situation, what we need to do is to change the water, which can improve the water quality, but also pay attention to cleaning up the dirt in the water.You should also feed less in order to prevent this situation from happening again.
1, strengthen the filtration: fish is best equipped with a filter, filter system perfect, the foam will be much less.Filtration methods are usually divided into two kinds, one is physical filtration, which can suck dirt into the filter tank, the other is biological filtration, which converts ammonia nitrogen into nitrate after organic matter decomposition, so that the amount of foam can be controlled.
2. Pay attention to changing the water: If there is no filtering equipment in the fish tank, you need to change the water regularly if you want to remove the foam.Usually change the water once a week, so as to ensure that the water quality will not deteriorate rapidly.When changing water, the water at the bottom needs to be pumped out by the water pipe, so that the dirt can be sucked away together to avoid decomposition in the water.
3. Control the amount of food: The fish needs to be fed, but the amount of food must be controlled. Feeding too much will not only damage the fish, but also lead to the formation of bubbles.Usually feed once or twice a day, each time to feed seven or eight full, this will reduce the amount of residual bait and fish manure, so as to better maintain water quality.
