The maxi would probably work just fine. If you really feel like spending some money though, I put an Ehiem Compact Pump 1000 in my 22 gal nano and am very happy with it. It is rated at 260 but it seems much stronger than a Maxi 1200. It is also adjustable so if you have something else to create flow in the tank, you can turn it down. I paid $29.99 for mine locally.

Good Luck,
Kevin
