i have a goldline control system with the turbo cel. my box display would read 2200ppm salt reading so i added salt (2 40 lbs. bags) but no change in readings so added more salt no change and water started to turn green so checked chlorine level and 0 chlorine then i had extra turbo cel so i installed it and it says hi salt. i drained water 3 times and still says hi salt and water is green. help!!!!!!!!!!!!!!!!!!!!
