The Waterbox AIO 20 Cube is a sophisticated, self-contained aquarium system designed to bring professional-grade reefing or aquascaping to any desktop or small space. Measuring 450 x 450 x 450 mm, this 20-gallon (76L) system features a built-in filtration compartment at the rear, keeping the display area clean and free of bulky equipment. Constructed with Starphire Ultra-Clear™ glass, the AIO 20 Cube offers unparalleled clarity, making it the perfect choice for high-end nano reefs, shrimp colonies, or lush planted displays.
The AIO (All-in-One) series eliminates the need for external plumbing or sumps, making it an ideal entry point into high-performance aquarium keeping.
Starphire Ultra-Clear™ Glass: Low-iron glass on all viewing panels provides maximum color neutrality and light transmittance for a crystal-clear view of your livestock.
Rear Filtration Chamber: A multi-stage back-chamber conceals the return pump, heater, and filter media, allowing the 45 cm cube display to remain the focal point.
Precision-Cut Overflow: Features a laser-cut weir that efficiently skims the surface of the water, removing organic films and improving gas exchange.
Adjustable Return Nozzle: Includes a directional flare nozzle to customize flow patterns, ensuring no "dead spots" exist within the display area.
Professional Seam Work: Assembled with high-strength translucent silicone and diamond-polished beveled edges for a seamless, minimalist appearance.

What is included with the "Aquarium Only" version? This package includes the rimless glass aquarium with the built-in AIO filtration chamber, the return pump, plumbing, a filter sock, and all necessary mechanical/chemical filter media. Lighting and stands are sold separately.
Can I run a protein skimmer in this tank? Yes. The rear chambers are designed to accommodate many popular nano-sized protein skimmers. This makes the AIO 20 Cube an excellent choice for a dedicated saltwater reef.
Is it difficult to clean the back chambers? The chambers are wide enough to allow for easy access with a small brush or siphon. Periodic cleaning of the back area is recommended to prevent detritus buildup.
Does it come with a lid? The AIO 20 Cube is an open-top, rimless design. While it does not include a lid, many hobbyists opt for a custom mesh or glass cover to prevent fish from jumping.
Waterbox Mesh Lid 4545: A custom-fit lid designed specifically for the 45 cm Cube to keep your inhabitants safe.
AI Prime 16HD Reef/Freshwater: The industry-favorite LED light that can be easily mounted to the rim of the AIO 20.
Waterbox AIO 20 Cabinet: A marine-grade, water-resistant stand that perfectly matches the footprint and aesthetic of the 20 Cube.
