Great start! We all know how this will turn out, it going to be beautiful just like you!
Did you use live rock or aquaforest seeded rock? Looks like a lot of non acro sps in there, will it stay that way or are they just tester corals? I would put the birdsnest on the sandbed so it doesnt take up all the room the acros need on the rocks. I treat them like I treat monties.
