I do 2x2x2x2x2x2 and feed mysis. Day one of new water of each set I feed light. Day two a few hours before transfer I feed heavy. My goal is to keep ammonia from building up so I transfer every two days and the heavy feeding a few hours doesn't cause problems with left over food since they are getting ready to go to a new bucket.
BTW, after a transfer I dump a little bleach into the dirty bucket with the heater and airstone still in there, then I rinse with fresh water, then dry. I'm confident the combination of bleach, fresh water, then dry, will kill all crypto that's come off the fish (I use two sets of equipment to run this, 2 buckets, two air stones, 2 heaters so everything can dry).
Only fish I've lost so far is a wrasse that jumped out of the bucket. Recommend a cover of some sorts.
