It sounds like you had multiple pests - which would be highly probable due to the fact that you have AEFW. Or something else was going on. The few people in this thread are the first that I've ever heard of them consuming anything but acros.
Parameters are perfect and I treated for Red Bugs and did the whole 5 week Levamisol regimen along with dipping and Egg hunting. Plus I finally just tossed any coral that was not 100% healthy. I have been in this hobby for 30 years and never before had any issues with these pests, And IMO the Whole Supply chain from Collectors to wholesallers and any seller that does not QT before selling to the public just adds to this problem.
And Constant dipping is not a path the Coral can stand for very long as it will degrade it's ability to kill these bugs due to constand exposure to these treatments and the bugs become imune IMO
