Our Filter Socks Help Keep Your Aquarium Clean and Healthier 

The interlocking micro-denier felt fibers are perfect for trapping uneaten food, waste excreted by livestock, decaying plants, detritus, dust, and other floating particulates.

Changing filter socks regularly increases water quality by removing collected solid organic compounds before they continue to break down and add additional nutrients (which can increase algae growth) to your aquarium water.
