I've heard of people not putting paper in the tank thinking that is what causes sensor readings, build-up, etc.
I think it is just a nasty plan to have soiled TP, even in bags in the house, maybe for hours before taking to the dumpster. After all...how many times a day do all of us use the toilet??? That's a lot of trips to the dumpster!
We use biodegradable blank tank products if we can find it or just plain water. Paper, with proper amount of water will dissolve just fine in a tank.
We generally don't use bleach in our black tank either because the natural process to begin breaking down paper and waste is by using bleach.
