Red Sea’s 100 & 225 micron aquarium Felt filter bags

Available in 2 porosities, the felt filter bags are very effective at trapping particulate matter in the thick wall of the bag.

100 micron felt filter bags are designed to provide fine ‘polishing’ of water that is already low in particulate matter (mature aquariums).

225 micron felt filter bags are ideal for regular day to day use and enable a longer period between cleaning than with the 100 micron bags.

Red Sea’s 225 micron Thin-Mesh aquarium filter bags

225 micron thin-mesh aquarium filter bags are perfect for new setups and after heavy maintenance or whenever there is a lot of particulate matter in the water. They are also suitable as a holder for other mechanical or chemical filter media. The monofilament construction of these bags makes them very easy to clean. These bags are now used in REEFER and MAX-S Systems
