What I suggest is get rid of the hood. I personally think it's ugly. The lights that you have are not suited for SPS or clams. You can keep zoathis, some lps, leather corals, but nothing that requires strong light. Since the tank is soo new, I would first get my cal, alk, and mag to natural sea water levels, and make sure they stay there. Get a good protein skimmer ( i know you choices are limited on a biocube). Get your phosphate and Nitrate as low as possible. Once your tank is stable, the light I would get is the ai sol super blue with the ai controller(the black casing) and hang it over the tank. Some people might tell you it's too strong, but you can regulate the light intensity. I have the same tank, and I got really frustrated at the tank design because you are limited to what you can do. I tried to attach a pic of mine, but browser keeps crashing, I wrote this post 3 times already. lol..
