Red Sea Reefer Fine Felt Filter Socks White 4 In X 10.5 in

These thin - mesh aquarium filter socks in white are ideal for new aquarium setups, post - heavy maintenance, or when there's a high amount of particulate matter in the water. They're also great for holding other mechanical or chemical filter media. Thanks to their monofilament design, they're super easy to clean.

To use these filter socks, simply place them in your aquarium's filter system. They work best when the water flow is directed through them. When you notice a significant buildup of debris, it's time to clean them. Cleaning is easy: just rinse them under running water until the water runs clear. As for maintenance, it's a good idea to check them regularly for any signs of wear and tear. If you see holes or significant damage, it's time to replace them. Avoid using harsh chemicals on the filter socks as this can damage the monofilament construction.
