We will have both Bayer Insecticide and Revive Coral Cleaner available at the meeting if you don't already have these. Below are instructions for there use.
ReVive: (from the label):
Directions: Mix 4 capfuls of Revive per gallon of clean, aged seawater at room temperature in a bucket or other container suitable for bathing the coral. Bathe coral in this mixture for at least a few minutes, up to 15 minutes, while gently swirling it or using an air stone for agitation. After the bath, remove coral from the mixture and place it in a saltwater aquarium with moderate water flow. The mix may be discarded, or it may be used for cleaning other corals. Discard the used mix after 1 hour.
* note * I generally rinse in clean (untreated) tank water before returning to my tank.
Bayer Insecticide: (this is more of a home remedy that has been used in the hobby for quite some time)
I'm going to provide links from a couple sources as I take no responsibility for its use, or dose (and I'm sure neither does Bayer)
