You can check Eheim's website http://www.eheim.com/external.htm for their recommendations.

The ECCO 2236 sounds good. I am using an older model ECCO 2235 for my 3.5ft tank. The problem with the older series was the priming handle malfunction easily. I think that is fixed for the new series.

I have also used Classic 2213 for 3ft tanks.

Their power consumption of the ECCO series is so low (5W only) like a small internal pump.
