I wanna put a canister filter on my 55 but the smaller tanks I wasn't sure.i also cut my filter pads when i had my aqueon 55/75 hob filter to remove the carbon. now im using a fluval 306 and an api xp2 on my two planted tanks. no carbon just sponge media and some bio media ceramic tubes.
I have a 10 that I just finished cycling and picked up a 20 bowfront yesterday for $10depends on the size of the smaller tanks. they do make different sizes. i would recommend a canister on your 55. thats what both my tanks are and i love my filters. the tanks are in my room and im a very light sleeper the hobs were too loud for me.
