• •HIGH QUALITY AND REUSEABLE - 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. You will receive two 11.5 inch (flat) by 16 inch long felt filter socks with a 7-inch diameter opening.
• •CUSTOMER AND PROFESSIONALS CHOICE - Our 200 micron size polypropylene filter socks are BEST SELLERS - the top choice for my clients as well as my aquarium service technicians - and both chose 200 micron socks because they do not clog as quickly as others, yet they help ensure crystal clear water. These felt filter socks are constructed with durable polypropylene which lasts longer than those made with polyester.
• •IMPROVE WATER QUALITY- Our filter socks have interlocking micro-denier felt fibers that are perfect for trapping uneaten food, waste excreted by livestock, decaying plants, detritus, dust, and other floating particulates. Changing filter socks regularly will increase water quality by removing solid organic compounds before they continue to break down and add additional nutrients (which can increase algae growth) to your aquarium water.
• •TIPS AND RISK-FREE GUARANTEE! You will receive our professional cleaning Instructions included with your filter socks. 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.
