The fish tank pump does not need to be turned off. The function of the water pump is to form water flow in the fish tank, and improve the water quality through various filtering equipment. If the water pump is turned off, the filtering will stop, and the fish feces and residual bait in the water body will make the water turbid, which is not conducive to the cultivation of beneficial bacteria. So the pump should always be on, so that a good filtration system can keep the water better.
1. Physical filtration: No matter what kind of filter pump, there must be physical filtration, so as to clean up the dirt in the fish tank, mainly including residual bait, fish feces and mucus secreted from the body surface. This kind of filtration method mainly brings these dirty things into the filter material through the water flow, and then relies on microorganisms to decompose them.
2. Biofiltration: Biofiltration mainly relies on nitrifying bacteria. Because the organic matter in the water is decomposed by microorganisms, a large number of ammonia nitrogen will be produced, which is toxic to fish, so nitrifying bacteria need to transform it into harmless nitrate to fish.
3. Chemical filtration: Chemical filtration is to filter through various chemical reagents, such as flocculants, algaecides, etc. Generally, it is seldom used in family fish farming. Algae removal is also done manually, or some algae-eating fish are raised. Because the dosage is not well controlled, it is easy to affect the health of the fish.
