Felt Filter Sock 4 x 14in with Plastic Ring

Felt Filter socks are an efficient first step in the filtration process of an aquarium. They should be positioned so that the filter sock is the first thing water pouring from the tank passes through. This assists in clearing the aquarium's water of food waste, trash, dirt, and other minute particles. By getting rid of the surplus detritus that would otherwise break down in the system, this considerably improves the water's quality while also reducing maintenance on pumps, sump cleanup, and biological filtration. The amount of organic waste that generates ammonia and nitrate will be lessened by regular use and rotation of the filter socks.
