Thank you all for responding. Im glad to hear that its healthy. My kenya tree has opened up all the way finally and it looks amazing.
If you're new to corals you might want to hit up the beginners forum, even if you're not new to saltwater. Quicker advice, lots of helpful folks. Though I think we did a fine job here.

Regardless, the key to having healthy corals, especially birdsnests, is to keep params stable. The most important being Alkalinity, or KH (Carbonate hardness). Calcium is also critical, and Magnesium needs to be high enough to allow both Alk and Calcium to maintain the correct levels.
For reading, RK mag, the articles by Randy Holmes-Farley are a great place to start.

Once you're an expert I expect you'll chuck all those softie corals and go full bore SPS. It's the final phase of the addiction, and the most expensive. Remember, never keep any receipts and NEVER tell the significant other how much you just spent on a fuzzy stick.
One more thing. I still have my Kenya Tree, my very first coral. I tried to remove it, and thought I did, but when I took apart my 40 gallon and moved things to my 150 I found it bunched up near the glass behind some rocks. it now lives happily in my 29 gallon where it is encouraged to spread at will.
