As far as the stabilzer step. What I have been doing is after a long rinse after fixing, I pour out the water, open the lid, take out my reel(s) and then shake out as much water as possible. Next, I pour the stabilizer in and I dunk each reel separately for the required time. This has eliminated two things. It eliminates the need to agitate (and the creation of air bubbles on my negs) and it helps me know that each roll has been fully submerged.
