My condolences. IMHO, aefw are the worst of the worst pests, as they are tough to eliminate completely and will eventually kill all your acros if you do nothing.
There are many different opinions on how to treat. Here's mine:
At the very least you should dip the ones you blew aefw off of. It is very likely there are eggs somewhere, usually on skeleton just next to tissue, generally out of the light (like on the underside or backside or in a branch crotch).
Your new goal is to eradicate all adults before they can lay eggs, breaking their life cycle. Each egg prolongs your agony another month or so (it takes eggs 21 days to hatch, and each egg can contain 3-7 aefw).
The most aggressive approach would be to remove all acros and to not put any more in the tank for months (starve them). The next most aggressive approach would be to remove and dip each acro. The least aggressive approach would be to do little other than baste and hope fish keep aefw populations under control.
I personally have found that aefw (because they consume acro flesh) irritate acros so their polyp extension and color decrease. I prefer more aggressive methods of treatment. The key is to keep dipping regularly (like every 5-7 days) to kill any newly hatched flatworms before they can lay eggs themselves. Treating a tank with a large number of acros is tedious and time consuming.
