HIGH QUALITY AND DURABLE - Our filter floss aquarium pad is CONSTRUCTED OF DURABLE POLYESTER FIBERS bonded by our special resin to give it EXCEPTIONAL STRENGTH. The lower section of our pad is made by taking layers of resilient fibers through a special process to tighten and entangle the fibers into a dense network producing a thin firm layer, perfect for removing fine debris. Our premium pads' consistent, reliable design gives SUPERIOR FILTRATION. IMPROVE WATER QUALITY- Place our DUAL ACTION POLYFILTER PAD in flowing water with the open weave side up to trap uneaten food, waste, decaying plants, detritus, and other large and fine floating particulates from the water. Changing filter media pads 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 the water in your fish tank.
