ClariSea SK-5000

The ClariSea fleece filter is a high efficiency water filtration system which effectively removes suspended particles such as micro algae, detritus, food, organic waste and  debris from the water column. Suitable for use in marine aquariums, freshwater aquariums, fish-breeding systems and propagation systems for corals.

A ClariSea filter will completely replace the need for high maintenance filter socks and result in crystal clear aquarium water.

The use of a ClariSea fleece filter will ensure the highest possible filtration efficiency for optimal light penetration to enhance growth of your corals and plants.

Continuously removes detritus & organic waste from the water column preventing breakdown to nitrate & phosphate in your aquarium.

The ClariSea fleece filter dramatically reduces the load on your protein skimmer by removing even the smallest of particles.

Constant filtration results in reduced maintenance of pumps, wave makers and protein skimmers, plus... no more socks to clean.

A ClariSea fleece filter will noticeably reduce the accumulation of detritus in your aquarium substrate and sump.
