Thanks for the info. I went to a pool supply store yesterday. I did not see this reply until, well, now........ The owner said two things that convinced me the bleach is the easy way.
Dichlor that she sold was granular. I wondered how hard would it be to disolve. Second, she commented that they are not using this chemical as much now. And she even said that there were a lot of teaspoons in a 1LB bag.......which was the smallest that they sold that had Dichlor in it.
So.....the FW tank is full with 1.25 cups bleach for 81 gals.
I saw in just one article that I read where the RV owner sanitized (bleach) the hot water heater..............complete with heating the water and letting it cool. Should the HWH be involved in the process of sanitizing? Mine is not at this point. The owner's manual makes no mention of the HWH in this process............?
Thanks again,
Eric
