If the water outlet of the fish tank is blocked, it needs to be cleaned immediately, otherwise it will affect the efficiency of the filtration system. Generally, it is necessary to use wire to hook out the dirt blocked inside, and then pour it out. It is worth mentioning that the blockage of the sewer outlet is generally caused by the problem of fish tank or water pump, which can only be completely solved by replacement. You can also try to add a wave machine, which can break the fish and facilitate the discharge of dirt.
1. Upper filtration: The upper filtration is the upper filtration, which is generally placed on the top of the fish tank. The submersible pump pumps the water from the bottom, through the upper filter tank, through the filter cotton, biochemical cotton and various filter materials, and then flows back to the tank from the bottom outlet. This kind of equipment is relatively cheap and easy to clean and maintain, but the filtering effect is general.
2. Bottom filtration: Bottom filtration is also called bottom tank filtration. It is placed at the bottom of the fish tank. It is usually divided into several compartments. Different filter materials can be placed inside. After the water flows through, the purification is completed. This filter is more suitable for raising some large fish, the power requirements of the pump is relatively high, but also may have a larger noise.
3. Filter cartridge: The external filter cartridge is also a common form of filtration. There are multiple filter boxes in the cartridge, and different filter materials are placed in each filter box, so that impurities in the water can be filtered out. Because the filter cartridge and the fish tank are separated, although the function is relatively good, it does not look very beautiful.
