7” Filter Media Cup
$19.99
A 7" filter media cup that sits in your sump's filter sock holder and holds loose media, sponges, or filter floss instead of a sock.
Why We Use It
It's a reusable alternative to filter socks: no weekly sock swaps, just rinse and refill.
Use: Fits standard 7" sock rings. Rinse media regularly so it doesn't trap detritus.
