I am about to close my pool. I had chlorine to the shock level to the pool three days ago with 3 gallons of chlorine.
I checked this morning the PH and it's very high, in the purple, and I have hard time to use the acid demand agent to get into the pink/red. It becomes blue and then turn yellow after 20 drops.
What should I do ?
