FAQ
Will this fit my Red Sea Max Nano?
No — this 10.5″/26 cm sock is for REEFER & MAX. For the Max Nano, use the Max Nano 225 Micron (2 Units) or Max Nano 100 Micron (2 Units).
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 fibers break down.
