Red Sea 100 Micron Felt Filter Bag

Red Sea's replacement felt filter bags are specifically designed for the Red Sea aquariums, making them fit perfectly in the Red Sea bag holders and preventing water bypassing the felt. They can also fit any standard 4" filter sock holder.

Red Sea's Filter Bags are available in two different materials (mesh & felt) and two different porosities (100 & 250 micron).

These 100 micron felt bags are for use with low particulate water and provide the most intense polishing of all the Red Sea filter bags, leading to crystal clear water.
