So I'm getting back into the hobby after a 10 year break. I'm setting up a 40 breeder. The only thing I'm undecided about is the lighting. This will be a mixed reef tank. Is a 24” 6 bulb ati t5 fixture to little. I'm worried it's I go 36" I will have a lot of spillage and to high par for softies and some lps. What would y'all recommend.
