Couple of points.
1. Nothing ever really dissolves in the black tank. If you don't believe it, just leave your contribution in your toilet at home and see how many days it stays there without dissolving. :E
2. As a most-of-the-time dry camper/boondocker, fresh water and tank conservation are of utmost importance. Even so, solids are always flushed with a full bowl of water. IF using a little less water really is the clog problem (still not convinced) I will gladly pay the cost with a little back flushing once in a while at the dump.
