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??
