it is not difficult to break the AEFW life cycle. the biggest thing is cutting the coral off at the base and anything that is not living flesh of the coral. AEFW DO NOT LAY EGGS ON CORAL SKIN. if you remove anything that isnt coral, dip the coral, fresh glue to a plug, and do weekly dips for a month, i promise you will successfully break the cycle. the biggest thing is dipping for a good amount of time without killing the coral, and while dipping, use a pump or turkey baster to keep constant turbulant flow over the acro, which will cause the AEFW to fly off.
AEFW have radula, which is the same thing snails use to scrape film algae off the glass of your aquarium. the AEFW use the radula to latch on to the coral skeleton, making them stick to the coral. turbulant flow as well as dip potency can make a difference when dipping to be successful at it
