FRAG 85.3 Aquarium System (54 Gallons) - Waterbox

Perfect for showcasing Shallow Reef Systems and designer Frag Tanks

The Waterbox FRAG series is the perfect foundation for creating the shallow reef tank or designer frag tank of your dreams! Its unique 16" height allows light to penetrate evenly with minimal shadows, making it ideal for growing out coral frags. Its low profile also provides for easy access to all areas of the tank for maintenance, reducing the need for clumsy grabber tools or wet shoulders. The included custom pre-fabricated plumbing system allows for quick assembly and utterly silent operation while remaining risk-free from floods.

• Dual adjustable return nozzles
• Ready-to-assemble plumbing kit, including:
  • Precision gate valve, safety drain, dual-manifold, and flexible return line
• Reef-ready sump system, including:
  • Two filter socks
  • Integrated RO Reservoir for ATO systems
  • Protein Skimmer / Media Reactor Chamber
  • Return Pump Chamber
• UV-coated cabinet stand with soft close hinges, push open doors, and leveling feet for lasting stability

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 FRAG 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 FRAG series overflow box features water-etched weir teeth and a sleek glass cover featuring the Waterbox logo.

Reef-Ready Sump System

The FRAG 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, an RO reservoir*, and a large section for a protein skimmer or reactor. Two filter socks are included in the FRAG series 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. Just add your favorite ATO system for days or weeks of hassle-free evaporation management!  

*The larger models (FRAG 145.5 & 165.6) do not include an internal RO Reservoir chamber in the sump. Instead, they feature a separate, external evaporation reservoir for easier maintenance.

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 gate 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 FRAG series even includes a dual-manifold, giving you additional valves for whatever optional equipment you'd like to incorporate. 

UV Coated Cabinet in White or Black

Each FRAG aquarium is paired with a UV-coated and durable cabinet stand made from solid plywood and supported by leveling feet for long-lasting stability. These cabinets are built to endure harsh and humid environments, and they even include soft close hinges that are PVC coated to minimize oxidation from saltwater. The cabinets have a modern look with recessed push-open doors and are available in either white or black finishes.
