I will be opening my pool shortly and I have a question on WHEN to test my pool. Once I get all the chemicals balanced out, I will be using a stenner pump to inject liquid chlorine twice a day. My run time on my pump will be 5am - 11am and 5pm -11pm and I'll be injecting the chlorine around 8am and 8pm. ( all subject to change but you get the idea ) My Question is at what time should I be testing my pool ? Before the chlorine injection or a hour or so after ? Any advice would be much appreciated.
Thank you
