Keeping an air pump positioned either at or below the waterline of your fish tank may cause water to back flow into your air pump. A check valve is an essential safety device that is used to prevent that from occurring. Suitable for cold water, freshwater tropical and marine aquariums. Dimensions: 5mm (3/16 inches) diameter in a pack of two.
