A closer look at the display
Ultra-Clear Glass
Built with 19mm thick ultra-clear glass panels for maximum durability, each aquarium is precision-bonded with high strength silicone to ensure a secure, watertight seal that stands up to the immense pressure of a filled system.
Custom-Fit Mesh Lid
Precision-designed for the REEF LX, the included mesh lid provides a secure barrier to prevent fish from jumping while maintaining maximum light penetration and airflow for a healthy aquatic environment.
Euro-braced with CNC Precision
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.
Effortless Setup,
Exceptional Flow
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.

Quick Connect Fittings
Durable, high-quality quick connect fittings make plumbing assembly fast, secure, and tool-free. Saving you time and ensuring a leak-proof setup right out of the box.
Precision Overflow Valve
A high-performance gate valve on the main drain line lets you easily dial in and maintain a silent, balanced siphon for ultra-quiet operation and stable water levels.
Dual-Manifold System
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.
Integrated Check Valve
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.
Engineered For Serious
Reef Keeping
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.
Refugium Chamber
Enhance natural nutrient export with the dedicated refugium chamber. A versatile divider plate allows you to expand or reduce the space as needed, making it simple to customize the refugium for macroalgae growth, copepods, or additional biological filtration.
Skimmer Chamber
The generously sized skimmer chamber is built to accommodate a wide range of today’s most popular protein skimmers and media reactors. No compromises—just the freedom to select the gear that works best for your reef’s needs.
External RO Reservoir
Paired with an ATO (Auto Top-Off) system, the external RO reservoir provides a steady supply of freshwater, maintaining consistent water levels and improving long-term stability. That means less maintenance and more time enjoying your thriving reef.
Strength Meets Style
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.
Aluminum Framing
Constructed with 30mm aluminum framing to easily withstand the weight and humidity of your aquarium system.
Leveling Feet
Adjustable, high-capacity leveling feet provide complete stability, ensuring your aquarium stays perfectly balanced in every direction.
