Glad to hear you're getting some results!! You're right--maintain your shock level until the CC is zero, the water is clear, and you're not losing more than 1 ppm of chlorine when testing at sundown and in the morning before the sun hits the pool. When you reach that stage, and let the chlorine drift down, remember that with a CYA of 60 you're still going to have to maintain a minimum chlorine level of 5-10. I would try to keep it around 7-8 just to be on the safe side and give yourself a little wiggle room in case of a rainy day or forgotten dose of chlorine.

Good job!
