Hi, I just got my first frag of some green acro about a week ago and it seems to be doing well in that it hasn't died yet? This is my first time trying out an SPS thats why I bought a small frag to see how it does. It's under a tek t5 fixture and I have about 40X worth of flow in my 29gal. My calcium is right around 400. When should I expect to see some growth and how can I tell if the coral is healthy and doing well. Any info for a newbie is very much appreciated!!
