What are Red Sea Micron Felt & Thin mesh Aquarium Filter Bags? 

Excellent for trapping free-floating particles, debris, and various forms of detritus, Red Sea Mesh Filter Socks are washable for continued use, continuing to give your tanks that crystal clear look. A range of 3 high-quality, reusable aquarium filter bags provides different mechanical filtration levels. These 10.5″/26cm long filter bags for Red Sea REEFER and MAX-S aquariums will also fit any standard 4″/10cm filter bag holder. Available in 2 porosities, the felt filter bags are very effective at trapping particulate matter in the thick wall of the bag.

How do Red Sea Micron Felt & Thin mesh Aquarium Filter Bags Work? 

Filter socks are most commonly used in sumps to help trap free-floating particles in the water that flows through the sock. The Red Sea Mesh Filter Socks are great for removing large pieces of free-floating material from the water that flows through the sock. Mesh Filter socks are a thinner material than felt, usually lasting a bit longer and easier to clean.


It is recommended to keep extra socks on hand and change them every couple of days for the best results. The Red Sea filter socks have a 225-micron rating to allow a majority of residues to be collected while allowing smaller particles to pass through the sock. We have found that filter socks with a micron size below 150 can clog quickly, whereas 225-micron socks can last a few days before they become clogged.


Potential Benefits of Red Sea Micron Felt & Thin mesh Aquarium Filter Bags

  • 100 micron felt filter bags are designed to provide fine polishing of water already low in particulate matter, otherwise known as mature aquariums. Provide fine "polishing" of aquarium water that is already low in particulate matter with the Red Sea 100 Micron Felt Fine Polish Filter Socks. These 10.5" long socks have a 4" ring and are compatible with Red Sea’s REEFER and MAX-S aquariums or any standard 4"/10 cm filter bag holder. These high-quality felt filter bags are very effective at trapping particulate matter, uneaten food, and waste in their thick walls, helping to eliminate organic matter that produces ammonia and nitrates. They are also washable and reusable, making them a great cost-effective option for your salt or freshwater tank. The filter bag is compatible with Red Sea’s REEFER and MAX-S aquariums or any standard 4"/10 cm filter bag holder. Measures 4" (10 cm) in diameter and 10.5" (26 cm) in length.

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