This is just my opinion, but I truly believe that tank is headed for some serious organics issues. Especially if you intend to keep SPS corals, I would take a serious look at the amount of sand and rock in that tank. That much sand in any display is a really really bad day waiting to happen. It will probably be fine for the first 3-5 years, but after that it's a ticking time-bomb. I used a coralife ss 125 for a while, and they're pretty unreliable long term, I would recommend switching to a higher quality skimmer with more capacity. I would also remove all but a very small amount of sand, to less than 1". The amount/type of fish you have in there is fine, IMO. I would definitely move some rock into the sump, and get that sand out of there before it bites you on the rear. My .02
