I have a 320w Razor over my 120g short (48x24x24). There's only a couple inches on each side of the fixture to the end of my glass. I'd like to replace the end 120 lenses with 90's. The guy at the LFS said I was crazy, first time he'd ever hear someone preferring the 90's.
Am I crazy? I don't think I need the 120 spread right on the ends of my tank and wouldn't mind making the light a little more concentrated there.
