Sump Specifications

Integrated Multi-Chamber Sump
The multi-chamber sump is designed for efficient filtration and flexible system configuration. A pre-filter baffle captures larger solids, reducing maintenance, while diffuser plates help minimize noise.

The adjustable skimmer chamber allows for precise water level control, while the third chamber can be configured for additional media or a refugium. An integrated ATO with a pre-installed float valve supports consistent water levels.
