Red Sea Max Nano 225 Micron Thin Mesh Filter Sock (2 Units)

Replacement 225 Micron Thin-Mesh Filter Socks for the Red Sea Max Nano aquarium. This pack includes 2 socks sized specifically to fit the Max Nano sump. The coarser 225-micron mesh flows fast and is ideal for newer tanks or systems with a heavier bioload.

Also available: Red Sea Max Nano 100 Micron (2 Units) for finer polishing, and the Red Sea 225 Micron Filter Sock for REEFER & MAX if you have a larger Red Sea system.

Will this fit my Red Sea REEFER or MAX?
No — this sock is sized for the Max Nano only. For REEFER / MAX systems, use the REEFER/MAX Thin-Mesh Filter Sock.

How often should I change filter socks?
Every 3–7 days depending on bioload. The longer they sit, the more they become a nitrate source.

Are they reusable?
Yes — rinse thoroughly or machine-wash (cold, no detergent fragrance). Replace once the fibers break down or stop cleaning up properly.
