Not quite so much to show for looks like a crushed plastic drum. The plastic drum was too weak and the pump has sucked the drum in on itself. One day I have to get around to re-enforcing it with some internal crossmembers. The main reason why i built it was to get things going quickly as I didn't have money for a decent canister and thought that the 30litre drum would easily surpass any canister on the market for biological media volume. I will be buying a proper canister for the moment (just for neatness) and having another look at it for when I get my 6 and 8ft tanks. I will deffinately throw up pictures when i do that of where I went wrong and what I will be fixing ie bigger intake and outlet, bigger pump, better spray bar and a few other little things.
Thank you for your interest though.
