The Reef Octopus Classic 100-HOB is a high-performance, hang-on-the-back protein skimmer designed to efficiently remove dissolved organic compounds from your saltwater aquarium. By creating a dense foam, it effectively extracts fish waste, uneaten food, and other pollutants before they can break down into harmful nitrates and phosphates. This process is crucial for maintaining superior water quality, promoting coral health, and ensuring a crystal-clear display for your reef ecosystem.

Engineered for performance in a compact design, this skimmer features a small footprint of just 8 by 3.25 inches, making it an excellent choice for systems with limited space. It is powered by the reliable Reef Octopus Aquatrance 1000s Pinwheel Pump, which consumes a mere 9 watts of power while producing an impressive air draw of 420 liters per hour. The combination of high air intake and a water draw of 350 liters per hour ensures a rich and stable foam production for optimal waste removal.

This protein skimmer is the perfect solution for aquarists with small to medium-sized reef tanks that do not have a sump. Its external, hang-on-back design allows for easy installation and maintenance without the need for complex in-sump plumbing. Backed by a two-year manufacturer warranty on the pump body, the Classic 100-HOB provides a reliable and space-saving filtration upgrade for any hobbyist seeking to achieve pristine water conditions and a thriving marine environment.
