Aqua One ReefSys 255 Aquarium

Bring elite optical clarity and modern design into your living space. The Aqua One ReefSys 255 is an open-top reef system engineered specifically to give you absolute flexibility over your filtration, lighting, and aquascaping layout.
The primary 3-foot display tank features refined, low-iron glass technology that removes the dull green tint of standard glass, ensuring your corals and marine fish are displayed in their mathematically truest, most striking colors. With an expanded 55cm front-to-back depth, this tank offers incredible aquascaping possibilities, letting you construct dynamic, multi-layered live rock structures with optimal swimming paths for active fish.
Tucked safely away inside the premium, soft-close cabinet is an intelligent, high-volume modular glass sump. Equipped with two height-adjustable plexiglass baffles (including one completely movable divider), the sump lets you dial in the exact water height and chamber dimensions required to perfectly fit your preferred protein skimmers and reactors. Water flows silently from the central weir into a specialized filter sock chamber equipped with low-splash silencers to eliminate trickling noises. Complete with an integrated precision gate valve siphon adjuster, a built-in auto top-up reservoir, and a fail-safe emergency backup drain line, this system delivers unmatched peace of mind and dead-silent performance.
