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. 



Rinse new filter socks with clean fresh water and wring them out before using them in your filter.

Our Experience

I owned an aquarium store (and separate aquarium maintenance company) for over 25 years during which I spent a lot of time and resources searching out and testing countless filter socks to find the best for my clients. Fortunately, one stood above the rest giving consistent and repeatable filtration performance in all types of aquariums. These long-lasting heavy-duty filter socks are the best the industry has to offer!
