The WaterBox Crystal Peninsula 7225+ is a flagship aquarium system designed to be the centerpiece of any luxury living or commercial space. Measuring 1800 x 650 x 600 mm, this "Peninsula" orientation allows for viewing from three sides, making it the ultimate tool for creating a massive room divider. Crafted from Starphire Ultra-Clear™ glass, this system provides a panoramic perspective of your reef, supported by a professional-grade glass sump and a robust, multi-stage plumbing system engineered for a system of this immense scale.
The Peninsula 7225+ provides the stability and volume required for the most advanced coral reefs and large-scale marine fish communities.
Starphire Ultra-Clear™ Glass: Constructed with 19 mm low-iron glass, providing incredible structural safety and 91% light transmittance for undistorted, true-to-life colors.
Side-Mounted Overflow: Unlike standard tanks, the overflow is located on the short end of the tank, maximizing the longitudinal aquascaping space for a seamless "endless reef" look.
Dual-Manifold Plumbing: Features a professional-grade plumbing kit with a precision gate valve, allowing you to easily divert flow to reactors, chillers, or UV sterilizers directly from the main return.
High-Capacity Sump: The integrated glass sump features four 100 mm filter sock silencers and a massive skimmer chamber to handle the bioload of a 900+ liter system.
Marine-Grade Plywood Cabinet: The 900 mm tall white cabinet is built with high-density, UV-coated plywood and features waterproofed internals to withstand the humidity of a large sump.

How many people are needed to move this tank?
Due to the 19 mm glass thickness, the empty glass tank alone is exceptionally heavy (approx. 200+ kg). Professional movers or at least 6-8 people with heavy-duty glass suction cups are required for safe installation.
Can the overflow be moved to the other side?
No. The Peninsula series is manufactured with a fixed overflow on one end. However, the cabinet is finished on all sides, so the tank can be oriented to face whichever direction fits your room layout.
Does it include the lighting mount?
Standard WaterBox systems do not include lighting or mounts. For a 6-foot Peninsula, most aquarists use a ceiling-mounted or floating rail system to maintain the clean, rimless "island" look.
Is the white cabinet easy to clean?
Yes. The cabinet features a UV-cured high-gloss finish that is resistant to salt creep and water stains. Wiping it down with a damp microfiber cloth is usually sufficient.
Tropic Marin Pro-Reef Salt: Essential for a system of this volume to ensure consistent, pharmaceutical-grade water chemistry.
Ecotech Marine Vectra L2: A high-output DC return pump recommended to handle the flow requirements and head pressure of this 900L system.
Triton N-DOC Organics Test: For a large, high-investment reef like the 7225+, regular laboratory testing is the best way to prevent nutrient imbalances.
