Well I nixed my 20 gallon hex for a 29 gallon and have been looking into T5 fixtures. I don't know what to look for and I have 2 kids so don't really have time to look things up and compare. I know that I want a 4 bulb T5 but don't know who makes a good on. I'm looking for my best bang for the buck and something I can just plug in a go. I know that you guys and gals know what I mean and that you all have better answers than I do. My max spending is between $200 and $250.
