The Euro-brace design provides unmatched strength and stability while maintaining a sleek profile. Paired with a custom-fit mesh lid, it perfectly complements the 19mm ultra-clear glass panels—delivering crystal-clear viewing with reinforced confidence.
Our professional-grade plumbing system is designed for effortless setup—snapping together quickly without the need for custom work—while still delivering the same high-performance flow and reliability as a fully tailored design.


Each system includes a dedicated manifold with multiple valves, giving you the flexibility to run additional equipment like reactors, UV sterilizers, or media filters without extra plumbing hassle.

A built-in check valve on the return line provides peace of mind by preventing backflow during pump shutdowns or power outages — protecting your sump from unexpected overflows.
The REEF LX sump system combines smart design with powerful functionality. A convertible filter sock chamber supports both traditional and roller filtration, complemented by a refugium for nutrient export and an external ATO for consistent stability.


Removable Sock Filtration
The REEF LX sump is designed with two oversized 7-inch filter socks for powerful mechanical filtration. When your system demands even greater efficiency, simply remove the socks and upgrade seamlessly to a filter roller system—giving you total control over how you filter your reef.

The REEF LX cabinet system is delivered fully assembled, built on a solid 30mm aluminum frame with modern exterior panels available in black or white.
Designed to keep your controllers, power supplies, and wiring organized and protected. This clean, purpose-built space allows for a tidy, professional installation—making it easier to manage your equipment while maintaining the elegant aesthetics Waterbox is known for.
