I jus turn my lights off float them for 15 min. drip them for 30 min. (doubling the water volume in the bucket I'm dripping him in) then put them in, turn on the lights an hour or so later. Some people will probably say to drip them for like 2 hours, but its my opinion that the longer you drip them the more stressed you will make the clam, but I definatley wouldn't cut out dripping.
