    Brown Stain

    Got the liquidator working fine with the advise from the great people here. Easily holds 8-9ppm (cya 70 from last year's pucks) at a setting of approx. 3 on the meter. Is anybody getting a thin brown stain layer where the pool water sits in the liquidator and no stain in the chlorine portion? Also getting the brown color in the meter. Touching it with a finger, it easily comes off of the sides. I'm guessing iron doing it,but that's just an uneducated guess. Any ideas??

    That is almost certainly iron precipitated out by the high PH inside the Liquidator.
