Save The Fish Power Filter Suction Barrier

Save the Fish Power Filter Suction Barrier creates a safe, clean and worry-free environment for your fish by protecting them from being sucked into your aquarium power filter.  It is designed for large and small power filter extension tubes and keeps your fish away from suction without reducing water circulation in your tank.  It works with hanging tank filters and canister filters and is safe to use on both fresh water and salt water tanks.
