Canisters in them self are fine, if you get one that's well made? I would have to say that you shouldn't be afraid to drop another $20 or $30 bucks and get one rated for say, perhaps 60gl to 80gl tank. I have found that having a filter that moves 2 to 5 times faster filtering rate for anytank bigger then 10gls to be a great help in keeping stock ALIVE and water CLEAR, just for starters. Good luck!
