Filtersocks are the most effective and convenient form of mechanical filtration. They remove excess food, detritus, organic waste, dust, and other particulates. Removing these particulates from the water column will reduce the amount of organic matter that produces ammonia and other undesirable substances in the aquarium. Filtersocks also help prevent larger objects, such as sand, crabs, snails, etc. from damaging pump motors. Regular filtersock use will lower organic levels and result in CRYSTAL CLEAR WATER !
