i use a fw dip and put about 10 drops of lugols in there and a few drops of fw exit...i keep them in that for about 5 minutes and then i swish them around for about a minute...then i look them over real good for any thing that might not have came off..and look for nudi eggs and pluck them off with twezzers...i then wash them off again and put them in the tank...i then run the actincs only for the rest of the day and most of mine will open that day some the might take a day or two...but i have never lost any using this..and i also use this dip if i see mine looking bad
