Waterbox's Most Dynamic Aquarium


Do more with your aquarium than ever before with the Waterbox INFINIA Series. With dimensions designed with aquascaping in mind, the INFINIA provides the ideal length and depth for optimal rock placement, so you can create the reefscape of your dreams. Waterbox also takes the guesswork out of plumbing by providing a quick, ready-to-assemble kit with everything you need to plumb your system in mere minutes. The included glass sump filtration system comes standard with refugium, skimmer, pump, and RO chambers, as well as filter socks and silencers. Finally, the INFINIA aquariums are paired with fully water-resistant MarineShield cabinet stands, crafted from anti-corrosion aluminum alloy and aluminum composite panels. The MarineShield stands are the most advanced Waterbox cabinetry yet, even including an electrical compartment to keep your power components organized and safe. With such advances in both form and function, the INFINIA aquariums are built for lasting impressions.

5D Rimless Low Iron Glass, Superior Craftsmanship

All Waterbox aquariums feature ultra-clear, low-iron Starphire glass that lets you see your fish and corals more clearly! Typical glass can block up to 20% of light passing through and can cause a yellowing effect, where Waterbox aquarium glass will allow more than 91% of light through. The increased light transfusion leads to more brilliant colors and an overall better-looking tank.

Like all Waterbox aquariums, the INFINIA series also includes strong straight-edged black silicone joints to create a leak-free aquarium. After assembly, every tank is water tested and inspected to ensure years of worry-free reefing. A pre-glued self-leveling mat is also included to minimize the effects of uneven surfaces or pressure points.


All Glass Overflow Box

Plastic overflow boxes can be a hassle, as they are hard to clean and can become brittle over time. That's why Waterbox aquariums feature all-glass overflows that can be cleaned just like the aquarium walls, with a metal-bladed scraper, saving you time and headaches. The INFINIA series overflow box features water-etched weir teeth and a sleek glass cover to reduce splashing and overflow noise.


Reef-Ready Sump System

The INFINIA series comes complete with a glass sump filtration system thoughtfully designed for your needs. The baffled sump includes chambers for filter socks, a return pump, a refugium, live rocks, and a large section for a protein skimmer or reactor. A separate RO Reservoir sits on rails above the sump for integrated ATO functions and easier maintenance. Filter socks and silencers are included to help polish your water from any free-floating particles, leading to longer pump life and cleaner water. The RO reservoir is perfect for holding freshwater for top offs to replace evaporated water in your aquarium. 



Custom Plumbing

Plumb your new tank in minutes with the included quick-connect PVC plumbing. Waterbox plumbing is made up of a mixture of rigid PVC, unions, and valves to give you a silent system, while also remaining safe from overflows and leaks. The pre-built sections make connecting everything super simple-- no plumbing knowledge required! The INFINIA series even includes a check valve to eliminate back-siphoning in the event of a power failure, as well as a dual-manifold to hook up additional reactors or equipment.


MarineShield Cabinet in Black or Silver

Each INFINIA aquarium is paired with an anti-corrosion aluminum cabinet stand with leveling feet for ultimate stability. Its strong, aluminum alloy brace and fully water-resistant aluminum composite panels combine to form one of the most stable platforms in the industry. The cabinet's soft-close hinges have been salt mist tested to ensure longevity in humid saltwater environments, and the designers at Waterbox have even included a built-in electrical compartment to keep all of your power supplies safe and organized. The Marineshield cabinet stand is one of the most advanced in its class for the serious reefkeeper, but you don't have to trade looks for function-- these modern beauties with recessed, push-open doors come in both sleek black and brushed aluminum silver finishes to compliment any room.
