fish tank does not circulate. The first is the electrical problem, which is the power failure, which causes the pump to stop working. It is also possible that the pump itself has problems, or the impeller is entangled by debris, which needs to be cleaned up in time. Or if the water inlet and outlet pipes are blocked, you can turn off the water pump and check it. If so, just empty it. Or the clogging of the filter material, usually the filter cotton, indicates that it is time to clean.
of filtration? 1. Physical filtration: Physical filtration is essential in the filtration system. It is mainly responsible for filtering impurities in water. The most commonly used filter material is filter cotton. However, it may be blocked if used for a long time, so it is better to clean it regularly. Cleaning can not use new water, it is best to use the original tank water to flush.
2. Chemical filtration: There are many filter materials for chemical filtration, such as activated carbon, ammonia-absorbing stone, volcanic rock, etc., most of which are responsible for adsorbing harmful ions in water. However, it should be noted that these filter materials have a certain timeliness, usually every 1-3 months to change, otherwise the saturated filter material will emit harmful substances.
3. Biofiltration: Biofiltration mainly relies on nitrifying bacteria. In addition to turning off the lights and exploding oxygen, the artificial culture of nitrifying bacteria also needs to prepare a bacterial house, so that nitrifying bacteria can attach to it. It should be noted that the bacteria house can not be moved easily, otherwise the ecological cycle in the tank will be destroyed.
