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.

"I researched reef tank offerings extensively before pulling the trigger on the R90. Zero disappointments with the whole setup! Aesthetically perfect. The doors are easily pulled from their magnetic fasteners. Cord management system is a nice touch as is the small drawer. Delivery was fast and well protected on its shipping pallet."
— Rick K. (5/5)
Beautiful in looks & engineering
"I am all praise and have not one criticism concerning the UNS R150. It’s just excellent in every way. For me, the best features are the already assembled cabinet with a great sump and magnetic doors. I also love how beautifully all of my electronics fit comfortably in the area set aside for it. It hides everything perfectly. My only suggestion would be to have a large paper getting started Guide."
