The OASE CrystalSkim quickly and effectively frees the aquarium surface of biofilm, floating plant debris and substances. It eliminates any biofilm from the water's surface. Removing biofilm is important for proper oxygen flow in an aquarium. Designed to catch even the finest plant debris that are almost impossible to remove with a net.
The CrystalSkim is a supplemental filter. It should be used in conjunction with either a power filter or a canister filter.
