Manufacturer Info

If you`ve ever used filter media inside a filter sock you know how water tends to bypass filtration materials like activated carbon and GFO. Maybe you`ve even given up using filter socks, leaving your filter frame unused. Why not switch to the Filter Media Cup instead?

The cup is designed to drop into a filter sock holder. The bottom of the cup has large holes so water flows freely through the media. The media cup works like a mini reactor.

There are several ways to use the media cup. You can fill it with bagged filter media, like activated carbon. It`s possible to use several types of bagged media, like GFO and resins at the same time. Putting a layer of filter floss or sponge on top of the media helps to evenly disperse the water and prevent channeling. Biological media works too.

We really like how easy it is to rinse fresh filter media, like activated carbon or resins. Just place the loaded filter cup under running water. Your hands stay clean and the media is washed and ready to use.

The filter cup is injection-molded in the US using food-grade, BPA-free polypropylene plastic, so no worries about being reef-safe. Give the cup a quick rinse with vinegar to remove any traces of mold release before use. An optional Filter Media Cup Adapter is available to accommodate C shaped filter sock frames or those with slightly larger diameter holders.

This Filter Media Cup opens up new opportunities to enhance your filtration system. You can even switch back and forth between a micron filter sock and specialized filter media for the best of both worlds. The cup and adapter ring fits most sock holders. If your curious if it will fit your sump, contact us and we`ll be happy to check!

REVIEW
This adapter definitely works great if you have a c style sock holder. I'm using a trigger ruby sump and this makes the cup fit perfectly. Without the adapter, the cup would be loose and possible fall through the holder. The adapter does what it needs to do and fixes this issue.
