Filter Sock Holder for Red Sea Max Nano
This cup fits the Red Sea Max Nano reef tank. It sits in the back chamber and holds filter floss or a bag of media, a simple swap for a cloth filter sock. The flared rim rests on the chamber wall and the slotted body lets water pass. Lift it out to rinse or refill. We print in PETG. Aquarium keepers have used it submerged for years. Rinse before use.

Common questions
How does the holder sit in my chamber?
The flared rim rests on the chamber wall, and the slotted body hangs down and lets water pass through. It sits in place on its own, without clips.
How do I know if the holder fits my tank's chamber?
Each cup is made for the chamber of the tank named on its product page. Find your tank model there and that is your cup.
What do I put inside the holder?
Fill it with filter floss or loose media, the same material you would put in a cloth sock.
Does the holder come out easily to clean or swap media?
Yes. The flared rim lets you lift it straight out of the chamber by hand.
