Thanks for the fast reply. I don't have a test kit that will measure chlorine that high. I can order one but what should I do meanwhile. how many pounds of the granular hypochlorite should I add to get it up? any suggestions. and I will shut off the chlorine feeder right now. and just sanitize with the hypochlorite until it is gone. then I am thinking of switching to bleach. does this strategy sound ok?
