- 2.7" 225 Micron Felt Filter Sock
Filter socks act as mechanical filters, trapping detritus, uneaten food, and other particulates, preventing them from decomposing in the water. Regularly changing these socks ensures a cleaner, healthier environment for the aquarium's inhabitants, contributing to better water clarity and overall tank stability. This sock is a direct replacement for the one included in the HelloReef 15 AND 33 Gallon Clownfish and Anemone Aquarium Kit.
