Saltwater Accessories / Polyester Reusable Zipped Media Bags
Filtration
A zipper, not a knot.
Heavy-duty 800-micron polyester bags with a real zipper — fill with any filter media, zip, rinse, and drop it back in. No tied-off socks, no spilled media.
Simple, but worth getting right
The kind of accessory you don't think about until it fails at the wrong moment.
Contains loose media securely
800-micron heavy-duty polyester mesh keeps carbon, phosphate remover, or any other loose media contained and out of your pumps and overflow.
No more tied-off socks
A real zipper closure means you can open, refill, and reseal the bag in seconds — no re-tying a knot every time you swap media.
Fill, zip, rinse, drop in
Fill the bag with your choice of media, zip it shut, give it a rinse, and place it in your filter or sump — no scratches to glass or acrylic, no risk to tank inhabitants.

There's no dosing here — just a quick setup.
