Pool is crystal clear. I tested 1.0 PPM FC, added 95 ounces chlorine for a target of 5ppm yesterday today 8pm its at 1PPM again. I shocked it previously with 3 gallons of chlorine about a week ago. I checked the CYA it was about 38. Is this normal consumption? Seems high to me compared to last year. In the 90's here with lots of sun.
