Pepere Posted May 26 Share Posted May 26 (edited) As a child in the late 60s everybody I knew used box filters. Poly fill on top with activated carbon on the bottom, air driven filtration. Fancy tanks had undergravel plates, but they were considered too expensive for the majority. I saw photos and descriptions of powered hang on back filters, but never saw one in real life back then. Never ever heard of a sponge filter back then. Were they used then? When did they become more common? And when did the Canister Filter enter common use in the hobby?
