can "granular chlorine" (sodium dichloro-s-triazinetrione) be used in the system either as a substitute for dichlor or bleach? what would be the disadvantage? I am draining my hot tub now (has been a headache for the first 6 months, found this site and am hopeful), and have granular chlorine at home (spa store sold it to me) but no dichlor. also, if I really need dichlor, is their an "everyday" store that i could get it tonight? ie walmart, lowes, etc. . .
