4" Filter Media Cup

The Red Sea 4" Filter Media Cup is a 4" x 8" acrylic cup (1 L capacity, fits 4" filter sock mounts) that replaces filter socks with a customizable media tower: slots in the bottom half force water down through packed media before it can exit. It runs carbon, GFO, filter floss, ceramic media, or biological substrates like MarinePure with the included 5" x 10" REEF SPEC media bag; works with Red Sea REEFER and most MAX systems (excluding MAX Nano) and most pre-made sumps.

Price: $17.95 USD
