I use Revive to dip. I usually double the dosage. I'll add the revive to my dip bucket, baste heavily for about 30 seconds, let the coral sit in still water for about two minutes and baste again for another 30 seconds. i had to scrape two red bugs off of the coral. kinda harsh but it worked. Plus this was such a small frag that there wasn't much room to hide. If it were a larger frag/colony it would be a lot easier for the bugs to crawl into polyp holes and make it through the dip. In that case i would QT until i thought the coral was ready to go into the DT. HTH
