The Reef Octopus BH-90 Hang On Skimmer is an innovative external protein skimmer designed specifically for saltwater reef aquariums, efficiently removing organic waste before it breaks down into harmful nitrates. Its unique siphon-fed cylindrical main body reduces pump load while maximizing air production, effectively eliminating unsightly surface oil film that can impede light penetration and ensuring cleaner, healthier water.

This skimmer boasts a sophisticated design featuring a cylindrical reaction chamber, a bubble chamber, and a gentle conical body-to-neck transition, all working together to minimize turbulence and optimize organic collection into the cup. Setup is straightforward, with two adjustable PVC screws ensuring stable fixation on your aquarium. Key specifications include a 4-inch body, a compact 7.5" x 7.5" footprint, and a total height of 23.8 inches, powered by an efficient Aquatrance 1000s Pinwheel Pump drawing 9 watts, 420 lph air, and 350 lph water. It comes with a 2-year warranty on the pump and 1 year on the skimmer body.

The BH-90 is ideal for reef enthusiasts seeking a high-performance, space-saving filtration solution for tanks up to 100 gallons with light demand, 90 gallons with medium demand, or 75 gallons with heavy demand. Its ability to skim the water surface makes it particularly beneficial for maintaining pristine water clarity and maximizing light penetration in sumpless systems or those where internal skimmers are not an option, providing robust organic removal for a healthier reef environment.
