I operate a 60k gallon inground outdoor pool in the PNW. I'm getting mobbed on the hot days and my chlorine flat out drops. I'm trying to avoid using cy acid as the last caretaker here was able to avoid it. What's the best method to add chlorine during a busy day? I have a auto feeder that is cranked up during these times and I usually open with 3 ppm chlorine. Cheers
