Very good experience, just go very slow, and observe how the corals react... SPS can go light on you quickly, have a plan to supplement aminos to provide the corals with nutrients. I would also begin running carbon in a reactor. Your skimmer will more than likely begin producing more skimmate and darken too. This will give you evidence that nitrate and phosphate are being exported from the system, which is indicated by water that appears crystal clear. If you dose too much, the tank will become cloudy, at this point the carbon will only assist, try not and get to that point, take it slow..... Good luck...
