Do not get the 20 NEP T5 fixture. I have it and love the fixture, but hate there is no bulb choices. a 24" model should be fine. Lots have run them on smaller tanks. The 150w lights do not seem to cause too much evap. 250 will start too, but again, lots of people use them without issue. As far as evap goes, a go ATO is essential regardless of lights, so evap is not a big issue.
