Hey Patrick, check out the corals section of my website. I have mostly LPS corals. See if there is anything there that you are interested in, and I'll let you know what it requires for care, IMHO.

As for calcium, not a big deal with only a couple LPS corals in your tank. Victor's suggestion of Seachem's Reef Advantage Calcium (and Reef Builder) is a good one. They are what I use for my calcum supplementation (and Alk levels), although I am now switching to Kalk. Even though I dose it, it can just be mixed up in small batches and poured right into your tank. If you are doing water changes a couple times a month, you could just add it to your change water to boost the CA. It's not something that needs to be added daily, or even weekly for that matter. Just test the CA levels once a week, and add if necessary. Otherwise just continue to supplement at water change time.

As for "your tank being ready" I think it is fine. How is the Xenia doing? How are the other inhabitants? If they look healthy and are showing growth then why not? The tank is stabilizing (maturing), and you have the better lighting, I don't see any reason why you cant add another coral. You're doing everything slowly and in stages, and that's going to go a long way towards the sucess you're going to have.
