i too drip mine, depending on the amount of water that is in the bag depends on how long I drip for, i use a gallon pitcher for mine, pour the bag(dont just let the coral fall) into it, i usually do 40% bag water(unless it is a really tall frag) then ill drip till its full, 45 min-1hr on average. if its just a zoa frag or something that gets removed from the water by my LFS, ill usually just fill the gallon pitcher up some and place it straight in since it was removed to begin with or possibly wrapped in newspaper. this is where i add my iodine and flat worm killer so they get dosed before they hit the display but that usually takes about 15-20 min
