    Hello Folks,
    I too am having gray tank problems. Draining is very slow and seems to have the white semi-solid stuff others are talking about. Has anyone found a chemical that will dissolve the stuff ?

    I have been told that if u put come calgon water softener powder on the tank with some water when u r driving the sloshing action will loosen the sludge in both the grey and black......bought some myself but sold the camper before I could try it...calgon hard to find however....found mine at a google search and maybe u can find the % of calgon to water to make this effective....
    good luck!!
