i have 9mm lilypipes from aquaticmagic form ebay, for a zoomed canister, still havent set them up or anything so cant really review them for you, but they look pretty good quality i guess, glass is kinda thick,. i can take some pictures for you later. but i dont think a zoo med will work being below the tank. pretty sure it has to be level with the tank itself, i think the reason is that a canister that small is not strong enough for it to be below the tank itself. i cant tell you for certain though.
