i have tried the three major players in the dipping business, bayer, revive and coral rx. so far i love to use bayer on every single coral i acquire. IMO, using a quarantine for every single coral purchased is the best prevention of NOT introducing pest into your display. Bayer kills most pest but like you are asking, AEFW bears eggs and bayer does not kill FW eggs. so it is important to quarantine your frags and do another dip after a week after the initial dip to give the eggs to hatch then the dip will be effective for them before they start to lay eggs again. also important to do a visual inspection with a magnifying glass to really look for any kind of eggs on the coral. i don't even trust my frags being moved form my other tank to the other without dipping, how much more coming from someone who i don't know. i don't even trust frags coming from friends even if i see that their tank is pristine. good practice is, dip and quarantine every single item you acquire.
