4 Inch Filter Sock Felt
The Felt Filter Sock is made of thick floss material ideal for removing small particulates from your water column and the plastic ring is designed to fit most common sock holders. Filter socks are used as an effective first stage of an aquarium’s filtration process and should be placed so that water coming from the tank filters into the filter sock first, removing uneaten food, detritus, organic waste, dust and other small particulates from aquarium water. This dramatically improves water quality, reduces maintenance on pumps, reduces sump cleaning and lessens the load on the biological filtration by removing waste before it breaks down. The routine use and rotation of filter socks will help reduce ammonia and nitrate producing organic waste from accumulating.
