I don't use Acropower, but I do use Restor. I had a dying coral I got from a friend and I believe this stuff saved it. Then I got a tankfull of suffering corals and almost all recovered - again, I believe it was due to this stuff.
So - here's a little hint - Algae is not bad. It's good. In fact, it's great. I've been using an ATS and exporting excess nutrients but feeding my tank constantly.
Here's a couple of threads from a former dino sufferer - FEED YOUR REEF, FEED IT (spoken with an Irish accent like the guy who advertises "feed your lawn, feed it").

It's not really dirty if you export the excess and it's healthy if the biofauna in the algae promotes health.
It's the difference between being a weakling who never goes outside - or an athlete who goes out and gets dirty, then takes a shower to get clean. Both are clean in the end, but which one is healthier?
