I'll assume they're on your aquascape and encrusted onto rocks, you're going to want to remove them from the rocks. Is possible pull the rocks from the tank, inspect thoroughly for eggs and scape them off. Dispose of the bases, the idea is you need to dip every single piece of acro. After you've done that, you'll want to dip all your sps once a week. Bayer is good, coral rx is good but be very careful with smooth skin acros. Rinse them off very good. I would use 2 rinsing stations. Then back into the tank. Assuming you remove all the eggs and dip all the sps, dip for 4-6 weeks every week (preferably 6). Then dip another 4 weeks, every other week.
