Want to improve water quality, the best way is to strengthen filtration.Usually there are two kinds of filtration, one is physical filtration, which is mainly responsible for absorbing particles and dirt in water, the other is biological filtration, heterotrophic bacteria can decompose it, the ammonia nitrogen produced is converted into nitrate by nitrifying bacteria, so it will not cause harm to fish.
Fish farming needs to change water, regular water change also helps to improve water conditions.Usually, the water exchange cycle is related to the maintenance ability of water quality, if the water quality is easy to deteriorate, the water exchange will be frequent, but the fastest can only be changed once in three or four days, and can not be changed more, up to one fifth.If the water quality is maintained well, it can be changed once half a month, at this time, it can be changed more, but not more than one third.
If there are too many fish in the fish tank, the amount of excretion is too large, the water quality is not easy to maintain, and the oxygen consumption is relatively high, the best way in this case is to reduce the number of fish, fish out some fish into other containers, or change to a larger fish tank, more water is easier to maintain water quality.
If you feed the fish too much food, the residual bait will decompose in the water, which will also lead to a large number of microbial reproduction, and even promote the outbreak of algae, which will lead to turbidity in the water body, and the way to control it is to reduce the amount of feeding, the fish are relatively hungry, feed twice a day, do not feed too much each time.
