Here's a few things that popped into my head when i read your rundown. If your acans, montis, zoes, etc are doing fine and your acros are not, I'd look at a few things. Since the easier stuff is doing fine, I'd look at lighting, flow, and filtration.

First off, I'd stop dosing most of your kent products asap till you know what's going on. What products are you using?

What is your in-tank flow situation right now. You post says your working on it.

Didn't see your filter setup listed. Are you using a sump with a skimmer and any other filter media?

Lighting could be the issue also. I have acros that thrive under 250w halides, but when I put them in my tank with the t5's they don't do well at all, even if I put them up near the top. If those frags you got came from a tank with halides, then they may not be getting the amount of light they're accustomed to in your tank.

Lastly, I lost all p.e. in my tank when I got AEFW. Have you been dipping your corals before they were placed in your tank?
