## Description

Regular use of these socks will aid in keeping your aquarium water clear and free from ammonia and nitrate as the organic waste is filtered out.   Felt filter socks give the best qualities of trapping free floating debris to give your tank water that crystal clear appearance. Felt filter socks with the plastic rings make replacement quick and easy, and most sumps will readily accept these filter socks. In most cases we suggest always putting felt filter socks in your sump. Filter Socks are used on overflows to remove small floating particles from aquarium water. This can dramatically improve water quality and reduce maintenance on filters that would otherwise become clogged. Felt Filter Sock is better at removing particles than mesh but can clog faster. Plastic ring fits common sump holders.
