The Reef Octopus Classic 150-INT is a high-performance, in-sump protein skimmer designed to provide exceptional water filtration for saltwater aquariums up to 210 gallons. As a crucial component of any reef tank's life support system, this skimmer efficiently removes dissolved organic compounds from the water column before they can break down into harmful nitrates and phosphates. Its reliable performance helps maintain superior water clarity and a healthier environment for corals and fish, making it a popular choice among discerning hobbyists.

Constructed from high-quality cast acrylic, this skimmer features a refined hybrid cone body that enhances foamate stabilization and collection. It is powered by a super-efficient Aquatrance 2000s pinwheel pump, which utilizes a venturi air injection system to generate a dense micro-bubble mixture for maximum waste removal. User-friendly features include a precision gate valve for easy water level control, a quick-release collection cup with a drain for simple maintenance, and an air silencer for quiet operation. The skimmer has a 12.4" by 8.7" footprint and stands 22" tall, operating best in a sump water depth of 6 to 8 inches.

This protein skimmer is an excellent investment for aquarists managing tanks with varying filtration demands, from a heavily stocked 120-gallon reef to a lightly stocked 210-gallon system. Its solid construction, proven technology, and ease of use make it suitable for both intermediate and advanced hobbyists seeking a dependable and effective filtration solution. The combination of powerful skimming and quiet, efficient operation ensures a stable and pristine aquatic environment, supporting the health of even the most sensitive inhabitants.
