The Reef Octopus Classic 110EXT is a high-performance external protein skimmer designed to efficiently remove organic waste from your saltwater aquarium. This unit operates outside of the sump or tank, making it a versatile solution for various system setups. By creating a dense foam of fine air bubbles, it effectively strips dissolved organic compounds, proteins, and other pollutants from the water column, resulting in improved water clarity, oxygenation, and overall health for your aquatic inhabitants.

This skimmer features a compact 5-inch body with a footprint of 10.4 by 9.25 inches, allowing for flexible placement. It is powered by the highly efficient and quiet Reef Octopus Aquatrance 1000s pinwheel pump, which consumes only 9 watts of power while drawing an impressive 420 L/H of air. The CLSC-110EXT requires an external feed pump with a suggested flow rate of up to 265 GPH and includes high-grade metric plumbing with US standard adapters to simplify installation.

Ideal for aquarists with limited in-sump space or those who prefer the convenience of external equipment, the Classic 110EXT is an excellent choice for maintaining pristine water conditions in a reef aquarium. Its external design allows for easy access for maintenance and cleaning without disturbing the sump or display tank. This model is perfectly suited for hobbyists who need reliable and powerful filtration to support a heavily stocked system and promote a thriving coral reef environment.
