Filter Media Cup - 7 inch - Flexible High Flow in Sea Foam White


Our 7" High-Flow Filter Media Cup will replace all those filter socks you have hanging around. Made out of a BPA free Polypropylene, this 7" Filter Media Cup is a solid one-piece design, that holds any filter media. The opaque color will easily hide any blemishes that may occur from changing out filter media.


The round design allows the Cup to slide into place, regardless of which “side “slides in first. The cup fits most round filter sock holders intended for use with 7" diameter filter socks. 


Simply drop the Filter Media Cup into your sock holder or filter tray, and fill with desired filter media. The beauty of the cup is you can use a wide variety of media types including filter pads, filter floss, carbon, GFO and biological filter media. To clean just replace your filter media as needed. You will no longer need to rinse and house used filter socks.

To reduce any noise produced by your Filter Media Cup, check out our reef-safe Filter Media Cup Silencer.

Note: GFO, Carbon, and other chemical filter media should be placed inside a media bag to prevent media from exiting the filter cup.

The Filter Media Cups do not fit inside Trigger System sumps using Single and Dual filter socks but will fit into the larger Trigger Systems sumps with a Triple filter sock holder. They will not fit Trigger Systems Sumps with an oval-shaped sock holder. As a precaution, we do recommend a thorough rinse with vinegar and water before placing into your filtration system.
