I've been using TanksTechRX. Cannot say good or bad about it, but knowing it is designed to use probiotics to break down the poo and not chemicals, Its probably a good choice. Time will tell.

I also use Tank RX, seems to be the best stuff so far. But along with it a day or so before we pack up I put in 1/4 cup of calgon powder and a capful of HE liquid laundry detergent in all the tanks. And we actually are NOT one of the "use lots of water" folks, we often dry camp for 1-2 weeks so the tank needs to last. We typically can go a week with DW and I, Daughter SIL and two teenagers. Thats with a 40 gallon black tank and two 35 gallon grey tanks.
