What to do about the foggy water in fish tank The foggy water in fish tank needs to be changed out, in order to change 1/3 of the water every other day, and change out most of the deteriorated water within a week. Also strengthen the filtration system of the fish tank and do repeated filtration until the fish tank water becomes clear gradually. There are many reasons why the water in the fish tank becomes foggy, such as too frequent cleaning of the filter material, resulting in less nitrifying bacteria; the nitrification system inside the fish tank has not yet been established; there are drug residues in the fish tank; the aging of water quality leads to protein worms breeding. In this regard, when raising fish, first of all, you need to raise good water, establish a good nitrification system, filter material cleaning and disinfection need to be carried out regularly. When using drugs, it is recommended to use the medicine tub alone and keep regular water changes.
