*NOTE: Please rinse all filter socks prior to first use

Filter socks are the most convenient form of mechanical filtration. They remove excess food, detritus, organic waste, dust, and other particulates. Removing these particulates from the water column will reduce the amount of organic matter that produces ammonia and other undesirable substances in the aquarium. Filter socks also help prevent larger objects, such as sand, crabs, snails, etc. from damaging pump motors. Regular filter sock use will lower organic levels and result in CRYSTAL CLEAR WATER!

Berlin Filter Socks

REVIEW
Okay. I ordered the filter socks. And what a dummie. I ordered 7" and didn't look at what that meant. Open the box today and I got 7" around thought it was 7" long. Called no hassle, receive and RMA. This is a great company. I'm a customer for life.
