Iodine dips don’t always get every parasite. This especially holds true for eggs. For example, Acorpora Eating Flatworms (AEFW) lay eggs on the branches of Acro corals. These eggs are not fazed by any sort of dipping method. The only way to remove them is through close inspection and manual removal, followed by quarantining the coral.
