white spots on acan's

[jcmelski]

What are these white spots on my Acans? How do I get rid of them? I noticed them today when I went to turn on the lights to my QT tank. I'll admit I haven't kept the qt tank up to par since I've been busy at work then the one weekend I planned on doing major tank cleanings(qt, 29bc and 110g) my family shows up from DC and I get stuck showing them around NY. the acans are now in my 29g BC. should I remove them and do some type of coral dip? I had them in a QT tank with different types of zoo's and a daisy coral(I think that's the name of it.) I wish I could get a closer pic but my camera doesn't let me zoom in too much.
