I just set up a 55 gallon Malawi rift tank with an Eheim Pro II 2026 canister filter, which I absolutely love. I can't even hear it! I'm currently setting up another 20 gallon, but I'm not sure that it's completely necessary to fork over so much money on such a filter for such a small tank. I am reluctant to buy another power filter since I’ve spoiled myself on the silence of the Eheim. I had an Aquaclear 110 on my 55 along with my Eheim, but I don’t remember it ever being quite as it quickly sucked up so much sand that it started grinding, so I took it off. Can anyone suggest a nice filter for such a small tank that could possibly compete with the silence of my Eheim, or should I just give in and put up with the noise of a power filter?
