The Frog @ease system works a bit differently that traditional chlorine. It is normal to have a high total chlorine and a very low free chlorine. Your readings are right inline with what they should be for that system. As for the milky water when the jets run, that could be a few things. High TDS will cause that. If you are using a defoamer, and a lot of it without cleaning your filter out, that will cause it. You say you have been shocking every few weeks and that the water is new, which one is it? How old is the water?
