I want the best quality of filter for a 55 gal. tank that is set in a wall (can't be overhang, has to be separate). A friend advised against gravel filters because they get all clogged up and are high maintenance. I wonder about the canister filters, especially the new ones that have just one canister--how do you know if all of the little parts in there are working the way they are supposed to? I've seen the three canister ones that seem a little more practical but they are way cheaper so I wonder about the quality.
