WATERBOX AQUARIUMS MARINE EX

Built with ultra-clear glass panels ranging from 10mm to 12mm thickness 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.

Engineered with an external overflow that relocates all plumbing to the back of the aquarium—maximizing internal display space for aquascaping while delivering a clean, unobstructed viewing experience.

A centralized overflow with dual return system streamlines water management while maximizing internal display volume—giving you more room to design expansive, intricate aquascapes.

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.

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.

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.

All Acrylic Sump

Designed for the serious reefkeeper, the MARINE EX acrylic sump system redefines what advanced filtration should be—precise, efficient, and built to last.

The spacious main chamber provides ample room for the industry’s leading protein skimmers and media reactors, giving you flexibility to choose the right equipment for your setup.

*Skimmer not included.

Water first passes through dual felt filter socks that effectively remove debris and particulates. Each sock sits in a removable tray, allowing for quick maintenance or seamless conversion to a filter roller system for automated mechanical filtration.

In each sump is an Integrated freshwater reservoir, designed to hold RO/DI top-off water. This built-in feature maintains consistent water levels and salinity stability, helping your system remain balanced and reducing the need for frequent manual top-offs.

Strength and Durability

The MARINE EX stands on a marine-grade laminated cabinet that blends durability with contemporary design. Clean lines, adjustable leveling feet, and soft-close doors create a premium look and feel, while the spacious interior provides easy access to equipment and wiring.

Choose from modern finishes that complement any home or office space—because your aquarium deserves a foundation as refined as the ecosystem it holds.

High weight capacity adjustable leveling feet ensure your aquarium is level, front to back and side-to-side.

Corrosion-resistant and durable, making them ideal for marine aquariums. They stand up to saltwater humidity, ensure smooth operation, and provide long-lasting reliability.
