Personally, I do not use bleach in my black tank. Not because I care a hoot about the life and loves of bacteria, I just don't think it is necessary. I do use 1 capful of liquid Calgon and 1 capful of Laundry Soap after ever dump.
I have just started using RV-Digest-It (RVD) in my gray tank. I use a "treatment" every 4-5 dumps to keep the grease down. No matter how hard you try, dish soap and grease just seems to stick where you don't want it to. After a RVD treatment; I follow up with the same Calgon and Laundry soap pretreat like the black tank now.
I have never had an odor problem that was not tracked down to be coming from the kitchen sink. Once it was a wet washcloth that was left in a ball in the sink; another was a smelly trap.
