If you keep the pump running, 30 minutes should be enough. That fact that you consistent never hit your target indicates something is off. Is the chlorine % correct in poolmath?How long do I need to wait after adding chlorine to test? Don’t I need to wait for it to mix with the pool water for a little while to get an accurate reading? I am just going off of the pole volume number given to me by the builder. From what I read, PH testing is probably not accurate right now during the SLAM process? I did some simple math based off my pool dimensions and average depth and it appears that 11.7k gallons is in the ballpark, at least.
Autofill has been off for about a week now. No change in water level. Will leave it off.
Just loaded up with 10 gallons of liquid chlorine, so I think I am set for a while now . I am going to up my FC target to 12 to stay on the safe side
