OK I'm just a FO convert so I'm still bouncing ideas around and trying to get my system set up right before I put anything alive in it. Anyway, I bought my 40Gal tank last week with a set of 4x36W PCs because I knew that you need a lot of light for inverts. Now a week later after I've spent hours reading this board, I think I'm going to take back the PCs and use the money to buy a 175W MH and 2 PC actinics, because I don't want to set up a tank and be limited in the kinds of stuff I can put in it because of lighting. Does this make sense, or am I just worrying too much?
