    Shock Levels

    I plan to shock my pool,but don't know which shock level to use. The cl/cya chart says 20 at cya at 50 and pool cauculator says 16 at cya at 50. Split the diff and shoot for 18 ? Thanks for Help.

    Won't hurt a thing to use the higher number and err on the high side.

    16 and 20 both work, 20 works faster.
