The WaterBox Silver Marine 35.1 is a high-performance, sump-based aquarium system designed for entry-level and advanced reef enthusiasts alike. This system combines a 450 x 450 x 450 mm display tank crafted from Starphire Ultra-Clear™ glass with a comprehensive filtration sump and a furniture-grade cabinet. By moving the filtration from the back of the tank into a dedicated cabinet sump, the Marine 35.1 provides increased water volume, superior oxygenation, and a clean, "rimless" aesthetic that puts the focus entirely on your reef.
The Silver Marine 35.1 includes professional-grade plumbing and hardware to eliminate the guesswork of setting up a sump-based system.
Starphire Ultra-Clear™ Glass: Features 8 mm low-iron glass with a 91% transmittance rate for crystal-clear viewing without the green tint found in standard glass.
Reef-Ready Sump System: Includes a multi-chambered glass sump with a dedicated skimmer chamber, pump chamber, and integrated ATO (Auto Top-Off) reservoir.
Quiet-Flow Plumbing: Equipped with a pre-cut, "no-glue" plumbing kit featuring a precision gate valve for silent operation and emergency overflow protection.
Furniture-Grade Cabinet: The 900 mm tall black cabinet is constructed from high-quality, water-resistant laminated plywood with soft-close doors.
Full Black Glass Overflow: A sleek internal overflow box that effectively skims the surface of the water, keeping it free of oils and debris.

Is this an All-In-One (AIO) or a Sump system?
This is a sump-based system. Unlike AIO tanks, where filtration is in the back, the Marine 35.1 uses a separate glass tank (sump) located inside the cabinet, providing more room for advanced equipment like larger skimmers and refugiums.
What is included in the box?
The system includes the Starphire glass aquarium, the black plywood cabinet, the glass sump, a pre-drilled plumbing kit, an ATO reservoir, and two filter socks with holders.
Do I need to buy a return pump separately?
Yes. Like most reef-ready systems, the return pump and lighting are sold separately so you can choose the specific brand and flow rate that suits your coral types.
Does it come in other colors?
While this listing is for the Black cabinet, WaterBox also offers this model with White or Oak finishes to match your home decor.
Tropic Marin Pro-Reef Salt: The pharmaceutical-grade choice for maintaining the stability this professional system was built for.
Sicce Syncra Silent 2.0: A highly recommended, quiet return pump that fits perfectly in the Marine 35.1 pump chamber.
AI Prime 16HD LED: The most popular lighting choice for this tank footprint, providing full-spectrum control for SPS and LPS corals.
