Now they absolutely dominate the “best of class” position; heads high! These easy to use canister filters are built with precision that German products are known for. Oase has been in the Aquarium and Pond industry for years and they perfected small volume with huge surface area filters to an art form! These external filters operate quietly while the water is filtered efficiently  through multiple media sizes and forms to give any aquarium a crystal clear water column.
