To keep it simple, I am going to put the Jandy 3way right in front of the chlorinator and T in the the return where I was thinking originally (in the long section between the chlorinator and the outlets.
As far as CYA, I have had the pump running for the past week and tested CYA. I got 30. I am going to keep monitoring it to make sure it stays under 60.
In order to get more chlorine when I am running the solar, I am either just add liquid (make look into a liquid pump) or just turn up the setting on the chlorinator (only at 3 of 5).
