remove all acropora sp. from display tank. Dip corals in revive, coral rx, or levamisole and repeat the dips found here on rc 5-6 times over the course or 2months. Or better yet, if the acros are just frags, just throw them away to be 100% you got rid of them and dont add any acros to the tank for atleast 2-3 months.
I just baste my acros with a turkey baster, or a maxijet. Fish eat what floats off. I'm sure I have a few floating around in the tank, but not enough to damage anything. If you have frags.. I wouldn't toss them, they are the easiest to treat and handle. Dips can be harsh I wouldn't dip anything unless you know that specific acropora can handle it. I found out the hard way when I initially over reacted to finding aefw.. Now it's been 8months since I initially found them. I haven't lost a single acropora to them since I started basting as my primary means of control, and dipping only the pieces that I find anything on and I am 100% certain can handle the dip.
Dont “toss your acros.” Thats obtuse. Good advice so far = turkey baster, wrasse, whatever lives lives sort of thing. Lots of successful people thrive with sps bugs. Just don’t destroy your tank trying to erradicate a perceived threat that isn't that bad.

Have you actually had AEFW? I have and lost thousands of dollars worth of acros, and turkey basting didn't do a thing. Like I said, if I was to get them again I wouldn't waste my time trying to live with them, it would be time to cut my losses.
Got rid of mine with daily basting, increasing the flow and adding several yellow Coris wrasses and 6-line wrasses. Been gone for 2 months. But this was just announced:

Looks interesting but pricey.
