I have had success with a Zoo Med 501 on that sized tank but I really think it's too small for 10 gallon. It looks like the 511 has double the flow rate which would be much more acceptable for a tank that size. I love my little 501, don't get me wrong, and would try a 511 if I needed a bigger filter.
