Im running halides on my 29 gal also. LPS corals growing like weeds! Tank is 2 months old and started with 3 heads on my acan, now it has 12. One month ago I bought 5 heads on a pink panther zoa, last night I had 12 heads. Thats just two examples. Do like the previous poster said, start them off in the sand and slowly move them up the rocks until they seem happy. Liveaquaria has good information on coral placement but its just a guide. Let the coral determine where its happiest.
