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!
