OK, Here is what you need to do. 1) Make sure you have a few gallons of water in the tank to start. An empty start guarantees a P&P Pile. 2) Use paper that actually dissolves. 3)Use TankTechRX treatment.
Just went for a week no odors, no issues. Plenty of water each flush, at least half a bowl, good paper, TankTech. Actually the tank had been in use two weeks prior, but had a very low level so I didn't bother to empty it. Was doing a bit of a test just to see if this stuff worked. It does. I might not do this in Summer, but Fall and Spring, no issues. Summer I am sure I'd dump more often.
