The first question I have is what kind of acans are you thinking about? Lords, echinata, bowerbanki, etc?
IMO Calcium is a bit high...I aim for mine to be around 410-440 ppm. I would also be a bit concerned about the PC lighting. Acans DO NOT require high lighting, but they do tend to show better colors under better lighting.
I have an acan lord dominated tank with T5's on it and I always buy browned out frags because I know under my lighting in my tank they always bounce back and make an amazing recovery.
Other than that I would say if you can find a cheap frag buy it up and see how it goes. Start the frag low in your tank and see how it does. Then move it accordingly. And make sure after about a week or two after introduction you spot feed them once to twice a week.
