This specialized 10 micron filter sock is specifically used to polish water beyond what a typical 200 micron filter sock can do, and more importantly, capture bonded phosphate particles when using liquid phosphate removing products. 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!

This 10 micron filter sock is not intended for extended periods and typically is only used as a temporary supplement to a 200 micron filter bag. Do not clean with bleach or other harsh chemicals. Rinse with water, allow to dry, and then reuse.


Inner Diameter: 3-9/16"
Outer Diameter: 4-1/4"
14" approx. length.

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

Thick Sock

The filter sock is great quality. I would not recommend this for any take with a heavy bio-load or heavy feeding. It clogged quick.
