you could pretty much keep any coral if you get your calcium a little higher. you didnt show test results for nitrite and nitrate, but with your discription, it sounds like you wont have a problem with those either. you could start with some easier corals like mushrooms, zoas, palys, and green star polyps. keep in mind, that those corals tend to take over once they are established, so you may want to have a plan for culling them or isolating them from taking over the entire tank. you could also put in leather corals of various kinds, just keep in mind that they produce some toxins that you may get built up if you arent running carbon. you could also start with LPS, since they are a little easier than SPS. maybe an open brain or a torch, frogspawn or hammer. i guess, it really depends on what you like. after a few months of keeping LPS, you probably would be ok with some SPS, just start with some of the hardier ones, like digitata and caps.
