Look, there are a million ways to "kill" an aiptasia... as soon as anyone ACTUALLY figures out a GOOD way of killing them, we wont need forum posts like this to debate what chemical works the best. (IODINE IODINE IODINE IODINE) Inject iodine directly into the stem of those little buggers and they wont have a good chance, but you can only do that once a week or maybe twice... its gunna take time bro... or just kill everything... cant take the easy way out of this one
