Fleece Filters

Designed to be mounted in a sump, fleece filters completely replace the need for filter socks and fine sponge filtration to make your aquarium water crystal clear! Clearer water increases light penetration providing even more light for coral or plant growth. As water flows through the fleece all but the finest detritus and organice waste will be removed which greatly decreases the likelihood of it breaking down into nitrate and phosphate in the aquarium, keeping water parameters level for longer.
