? The simplest way to prevent small fish from being sucked is to put a silk stocking on the suction port, which can not only ensure the flow of water, but also prevent it from sucking small fish. It should be noted that every once in a while, it should be replaced and cleaned, otherwise too much dirt will accumulate on it, which will affect the water flow, is not conducive to filtration, and even affect the health of fish.
of fish tank filtration? 1. Physical filtration: Physical filtration is a particularly important part of the filtration system. It is mainly responsible for filtering out impurities in the water, keeping the water clean and sanitary, and making it look clearer and cleaner. The filter material needed for this kind of filtration is filter cotton, which needs to be cleaned regularly and replaced after being washed thin because impurities will be blocked after being used for a long time.
2. Chemical filtration: The main filter materials used in chemical filtration are ammonia-absorbing stone, zeolite, activated carbon, etc., which can absorb harmful ions in water and have a good effect on maintaining water quality. It is worth mentioning that these filter materials are time-limited and will be saturated after a period of time, at which time they will be replaced.
3. Biofiltration: Biofiltration mainly relies on nitrifying bacteria, and the cultivation of nitrifying bacteria is indispensable to the bacterial house. Its function is to provide a place for bacteria to attach. It should be noted that the bacterial house can not be easily cleaned and replaced, otherwise the water quality is difficult to maintain, thus affecting the health of fish.
