Poolking’s aquarium prefilter is mainly composed of piping, tank, filter baskets, flange covers, and some parts. The prefilter can remove solid particles from the water and also protect the normal operation of subsequent equipment. When the fluid enters the prefilter, its solid impurities are blocked in the filter basket, and clean fluid flows out from the filter outlet through the filter basket. When cleaning is required, use a wrench to loosen the plug at the bottom of the main pipe, remove the flange cover, and take out the filter basket. After cleaning, it can be reinstalled, which is extremely convenient for use and maintenance
