I have a 90gal acrylic that's setup as a FOWLR and i would like to convert it to a SPS and clam reef tank, but i'm wondering if it's ok to put halides above an acrylic tank? Will they discolor and distort the acrylic over time? The tank is an Amiricle w 2 large openings on the top w all the edges being exposed to harmful UV. It's a nice looking setup but it is it practical for reef only purposes? Any thoughts? Steve
