ClariSea SK-3000 Gen3 Fleece Filter

The ClariSea SK-3000 Gen3 is the latest evolution in our market-leading, patented fleece roll filter system. Engineered with advanced R&D and customer feedback, the Gen3 builds on the success of the Gen 2.1 with even more user-friendly features, including a pre-built body, versatile multi-size inlet adapter, and easier fleece loading system.

Designed for marine aquariums, freshwater tanks, coral propagation, and breeding systems, this high-efficiency filter continuously removes suspended particles like detritus, microalgae, uneaten food, and organic waste — leaving your water crystal clear.
