Purpose-Built for Saltwater Reef Systems
The RedFlex Reef Sump is designed specifically for saltwater aquariums, combining organized filtration with a bold red and white acrylic finish. Water enters through the overflow port, passes through an integrated bubble diffuser, and flows into a 4-inch 200-micron filter sock for mechanical filtration. An overflow panel provides an added layer of protection, allowing water to bypass safely if the filter sock becomes clogged.
The refugium chamber features an adjustable flow gate that allows you to fine-tune water levels between 6 and 9 inches to match your skimmer's water depth requirements. Integrated dosing tube holders, probe mounts, and wire management help keep equipment secure and out of the way.
Additionally, each sump includes a flexible hose, a 4" filter sock, and a foam block sponge.

Bubble Diffusers
Built-in bubble diffusers help minimize bubbles entering the sump.

Probe & Tube Holder
Integrated holders keep probes and dosing lines organized and secure.

Adjustable Water Level
The water level gate makes it easy to set the right water height for your skimmer.

Cord Management
The power cord management clip in the return section keeps cords tidy and out of the way.
