To be honest the worst part is getting over that you have them and setting yourself up for the dipping process. The most foolproof way is to set up a QT tank for all acropora. When removing the acros you will have to either chip off , kalk paste, or epoxy over any encrusted growth on the rockwork to ensure the DT is acro free. I've read about some reported successes just dipping all the acros but leaving them in the DT. You still have to eliminate the encrusting growth.
I'm using the Bayer dip for 8 consecutive weeks while the DT remains fallow. It seemed for every reported success with CoralRX and Revive killing them there was someone else saying it didn't in their case. I couldn't find anybody that said bayer didn't work. I'm using 20ml per cup of tank water for 15 minutes. Reports for dosages and times varied wildly so I picked a slightly stronger dosage and longer time than average but nowhere near the extremes I've read. After dipping in the bayer solution I move the corals to a bucket of tank water with vigorous flow for 15 minutes, then a 3rd bucket for five more minutes. Standard procedure is one rinse but I'm still a bit nervous about using a pesticide. After 3 dips I have seen no negative reactions from any of my corals or other livestock. Now that I have the corals isolated it takes less than an hour to pull the corals, dip them, and return them to the tank.
