Core System Features & Innovations

• Eurobraced Ultra-Clear Glass: Engineered with glass thickness up to 15 mm (0.59”), high-grade eurobracing for superior structural integrity, and bonded with high-performance euro-silicone.
• Extra-Fortified Cabinets: Built from marine-spec laminated plywood to support the full contour of the display tank. Includes stainless steel hinges, leveling feet, and cabinet finishes in Black, White, or Classic Oak.
• High-Precision ReefGate Valve: A bespoke, heavy-duty gate valve installed on the downflow pipe that allows micro-adjustments for near-silent overflow operation.
• Hydrodynamically Superior Piping: Enlarged rectangular-profile downflow pipes maximize circulation and eliminate noise. Includes optional connector kits for both Metric and USA standard pipe customization.
• Central Overflow & Surface Skimmer: Conceals all return and drain plumbing within a sleek overflow box featuring removable surface skimming combs for quick maintenance.
• High-Performance REEF SPEC Sump: Includes a dedicated skimmer chamber with adjustable water height, a built-in bubble trap to prevent microbubbles in the display, and a plug-and-play ReefMat-ready mechanical filtration bay (fits ReefMat 250/500/1200, filter socks, and media cups).
