Red Sea Filter Media Cup – Customizable Filtration for Reefer & MAX Systems

The Red Sea Filter Media Cup is an ideal and cost-effective replacement for standard filter socks. This versatile cup allows you to create your own custom filter tower by packing it with filter floss, ceramic media, carbon, GFO, or any other media of your choice. The integrated slots at the bottom half of the cup force water to flow down through your media before it can freely exit, ensuring maximum contact time and efficient filtration.

Custom Media Options & Technical Specifications

Whether you are looking to remove toxins, lower nutrients, or polish water, the Media Cup provides the flexibility to adapt to your tank's specific needs.

Water Polishing: Place a few handfuls of filter pad in the cup to trap free-floating particles; simply replace the pads every few days for crystal-clear water.
Chemical Filtration: Use the included REEF-SPEC Media Bag to run carbon for removing toxins and yellowing pigments, or GFO to lower phosphate levels.
Biological Support: Add biological substrates like MarinePure to significantly increase the available surface area for beneficial bacteria.

Dimensions: 4" x 8"
Capacity: 1.0 L
