After a rather slow (2 hr) drip acclimation procedure, I give them a 6 hour Interceptor bath in a half gallon bucket with a tiny powerhead pointed UPWARDS. This creates a small fountain and assures I'm not subjecting anything to a laminar flow situation during this time. I'm sure I'm using at least 5X the Interceptor dosage because I can't measure low enough to 'correctly' dose a half gallon of water. The whole bucket is clipped to my frag tank, by the way, to assure the temperature is consistent with the system both during and after the bath.
After the six hours are up, I add 20 drops of Lugols to the same water and let it sit for another 15 minutes. Then I shake the piece and place it directly into my frag tank which is connected to my main system. I've left pieces in there from just a few days to several months and since I've been dipping this way (6-8 times), I have not lost a single frag.
