AquaLife 4" x 8" 200 Micron Felt Filter Sock with Plastic Ring
-The most convenient form of mechanical filtration
-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 unique model can also be used as a media bag. It's larger micron allows for debris to be caught while allowing water to flow through. Media like phosguard, pelleted carbon, and matrix are excellent choices.
Directions: Rinse before use. Filter socks are designed to be used inside a sump or refugium with a mounting bracket or hanging mechanism. Simply place filter sock in path of drain water. Allow water that enters the sump to fall directly into filter sock. Keep the plastic filter sock ring below the top edge of your sump to prevent overflow when filter sock reaches capacity.
Filter socks are reusable. Turn sock inside-out and thoroughly rinse with a garden hose. For best results use a high-pressure water nozzle. Rinsing should be performed when filter sock turns brown or when water overflows. Frequent rinsing helps to achieve optimal water quality.
Important: First time use of a brand new filter sock may cause increased protein skimming. Normal protein skimming function should resume within 24 hours. Be careful to monitor protein skimmer collection cup level so that it does not overflow.
