Mike brought my attention to this thread recently. We are very careful when new zoas and palys arrive in our facility. We use Revive and Coral Rx on the new pieces that arrive, however, as a member mentioned, these will kill the adult/hatched Nudis but not the eggs that it might have left. We do routine dips on all our frags once a week on the dot, due to the fact that these coral dips do not take care of the eggs. For coral colonies, we observe each piece daily. If we spot anything out of the ordinary, we treat it right away. We have 3 guys here that do our maintence and husbandry for our systems and making sure that pests are not on our corals is their top priority.
Lastly, I want to add that prior to our ship out, we do a quick revive rinse on every piece (not the full 5 - 10 mins that they recommend, just a quick rinse and a blast from the turkey baster).
I do agree with everyone though, no matter where the corals come from, definitely dip and inspect it closely before epoxying it into your reef
Thank you.
