The stuff Thetford recommended was Aqua-Kem, and it too seems to be discontinued. I hoarded as many single serve bottles as I could find when WalMart was clearing it out. I now have 80-something bottles. Stupid me, I was counting one bottle equals one night, not one dump. And now with the SeaLand I’m thinking about trying half bottle per dump since my tank is only 10 gallons and the bottle says it will treat a 40 gallon black tank.
