The Reef Octopus Classic 202 S is an advanced in-sump protein skimmer designed to deliver powerful, refined filtration for saltwater reef aquariums. Utilizing an ultra-efficient Aquatrance 3000s pump, this unit effectively removes organic waste and pollutants, ensuring pristine water quality for tanks with a light bioload up to 265 gallons, a medium bioload up to 200 gallons, or a heavy bioload up to 180 gallons.

Engineered for optimal performance, the skimmer features a turbulence-reducing Super Cone body, often referred to as a "wine glass shape," which enhances bubble contact time for superior skimming efficiency. Constructed from durable cast acrylic, it boasts a compact footprint of 12.4 inches by 10 inches and a total height of 23.2 inches, making it suitable for sumps with limited space and a recommended water height of 7 to 9 inches. Other notable features include a bubble dispersant plate, precision control for bubble-free output, and a design that fully disassembles for effortless cleaning and maintenance.

This protein skimmer is an excellent choice for reef hobbyists seeking high-performance filtration at an accessible price point, particularly those managing aquariums up to 265 gallons. Its efficient and quiet operation, combined with robust construction and ease of cleaning, makes it ideal for both new and experienced aquarists who prioritize reliable waste removal and long-term tank health without compromising on sump footprint.
