Aqua One ReefSys 434 Marine Aquarium & Cabinet – 434L Rimless Reef Tank

The Aqua One ReefSys 434 Aquarium & Cabinet is a large-format, premium marine aquarium system designed for serious reef keepers who want maximum visual impact without sacrificing clean, modern design. As part of the ReefSys range, it delivers exceptional build quality, minimalist aesthetics, and professional functionality at a competitive price point.

The low-iron rimless glass display tank removes bulky hoods and thick bezels, allowing uninterrupted viewing of your reef from every angle. This open-top design enhances light penetration, colour clarity, and depth—making aquascaping more creative and visually striking.

Supporting the display is a UK-manufactured, yacht-grade cabinet, engineered for strength, water resistance, and long-term reliability. The handle-less doors maintain a seamless appearance and feature a push-open, soft-close mechanism, discreetly concealing the adjustable innovative sump, which is included as standard.
