, it will produce a large amount of ammonia nitrogen after decomposition, which will cause toxicity to fish. Although ammonia nitrogen can be transformed by nitrifying bacteria, the number of nitrifying bacteria is limited, and the transformation is a drop in the bucket, which can not improve water quality at all. At the same time, due to the eutrophication of the water body, it will also increase the risk of algae explosion in the fish tank, and the proliferation of algae will also affect the health of fish.
1. Strengthen filtration: The best way to clean up the feces in the fish tank is to strengthen filtration. Filtration is divided into two parts, one is physical filtration, which can suck feces into the filter tank, the other is biological filtration, which mainly relies on microorganisms to decompose it, and the ammonia nitrogen produced is further converted by nitrifying bacteria, so that it will not cause harm to fish.
2. Manual cleaning: The cleaning efficiency of the filtration equipment is limited. If the amount of feces is too large, it must be cleaned manually. Every time you change the water for the fish, you can pump out the water at the bottom first, which can also clean up the dirt, and then add new water. Fish can also be fished out irregularly, emptied of water and then cleaned up.
3, raise clean fish: The sort that clean fish has a lot of, but the fish that cleans excrement is very few however, general only scavenger and a few special-shaped fish. These fish are benthic, with mouths below, which can absorb dirt from the bottom of the water, but they can eat and pull, so they can only be effective for a short time.
