Request advice: considering adding SPS corals to my LPS tank

[Samw]

Some other easy SPS would be Cactus coral and Hydnophora. I have no trouble with those even when they were only under 110W of PC lighting. Monti caps and Acros give me trouble all the time. My Acros have been improving lately with the addition of the Tunze Skimmer and new MH bulb. My dissolved oxygen level in the morning has gone up from 55% to 70%.
