Has anyone tried the Geo Method to sanitize their tanks? I know it takes powder laundry soap,bleach and water softener. My question is... what kind of water softener do you use. Thanks, Tom
We use whiteking and mix it up with hot water and pour in 5 gals. of water and the rest of the stuff. we hardly ever get close to filling up the black tank in 4-5 days. We try to fill up the black tank with the left over water we have and it seems to work.
