- CUSTOM MADE: Our filter socks are constructed only when our US factory receives our exact specifications; years of testing produced the perfect blueprint. Other socks may look like ours but if you want the best you have found them. You will receive fifty 4 inch by 8 Inch felt filter socks with a 4-inch diameter plastic ring that will fit most sump holders. THESE DO NOT FIT RED SEA FILTERS.
- HIGH QUALITY AND REUSABLE - Our aquarium felt filter bags or socks have interlocking fibers to trap floating debris, producing crystal clear aquarium water. Solid construction and heavy duty stitching make these socks STRONG AND DURABLE so they can be CLEANED AND REUSED NUMEROUS TIMES.
- REMOVES FINE PARTICLES - Our 100 micron filter socks remove much smaller particles from water than 200 micron socks to produce polished, crystal clear aquarium water. Since they catch such tiny debris they will clog up faster than 200 micron filter socks.
- SAFE FOR YOUR AQUATIC FRIENDS - Strict quality control ensures our filter socks remain aquarium-safe all the way from our USA manufacturer to you. You can now buy with confidence knowing that your filter socks will not come into contact with any harmful contaminants and will always arrive to your door safe for your aquatic friends.

In addition we are committed to our 100% CUSTOMER SATISFACTION so if you find that you are not 5-Star Happy with us or our products then please contact us and we will do whatever it takes to make sure you are 100% happy.
Our 100 micron filter sock with 4 inch ring is available in 2 other lengths: MEDIUM (10.5 inches long) and LONG (14 inches long).
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.

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!
