You recommended above when I told you I had decided to go with Ice Cap 660 (4 middle bulbs) and Triad (Dusk/Dawn) with Old Tek retro from Reef Geek on a 75 gal Std tank (20 inch deep). The reason I was going to 660 ballast is that corals just don't seem to grow well or pop colors. All water parameters are good. Acrylic tank and covers might impare par in tank.
Now I am having second thoughts. Would it be better to stick with standard ballasts, and upgrade reflectors to Reef Geek (could fit 6) or Aquatinics (could fit 7) instead of upgrading to Ice Cap 660 ballast? Would the colors and growth be washed out with the 660 ballast on a 20 inch deep tank? Ice Cap 660 ballast (used) would be cheaper than all the reflectors. I saw another thread where the guy used a 430 and 660 ballast on Ice Cap reflectors for his 90 Gal (24 inch deep) with the following bulbs and his corals looked great.
