Upgrade your aquarium's filtration game with a hang-on refugium, no sump or complicated plumbing required! The AquaMaxx HOB-R is incredibly easy to install and is compatible with pretty much any aquarium large enough to accommodate the full width of the refugium itself.  The acrylic chamber simply hangs off the back of your existing aquarium but can also hang on the side of your sump, it even works with AIO aquariums.

The benefits of a refugium can be game-changing, especially in tanks that struggle with elevated nitrate and phosphate levels. Via the growth of macroalgae, you can improve your tank's ability to export nutrients with the added benefit of providing prime habitat for beneficial micro-fauna such as copepods and amphipods. Maintenance is incredibly easy and with the HOB-R, you can have it installed and working in a matter of minutes.
