ClariSea SK-5000 Gen3 Fleece Filter

High-Efficiency Automatic Roller Filter for Crystal Clear Aquariums

The ClariSea SK-5000 Gen3 is the latest evolution of V2.1’s market-leading roller filter, now redesigned for even easier setup, maintenance, and long-term performance. With a pre-built body, universal inlet adapter, and redesigned fleece-loading system, the Gen3 is faster to install and simpler to maintain—no dismantling required.

This high-efficiency water filtration system continuously removes detritus, microalgae, food waste, gravel dust, and organic particles, providing brilliantly clear water while reducing nitrate and phosphate buildup. Suitable for marine aquariums, freshwater tanks, coral propagation systems, and breeding setups, it completely replaces messy filter socks with a fully automated solution.
