When it ask about temperature , is it out side air temp or water temp ? Outside changes a lot , water not as much - Does it really matter and if so is it that minute you test or better method to record ? My water is around 85'ish but outside can be over 100 in the day so want to check - thanks

It's water temperature - and water temperature affects the CSI calculation. Since you have a plaster pool and are in Arizona, you may wish to track your CSI. CH also affects the CSI.

OK, I do have 85 degrees listed plus track the CSI to see if it shows balanced once I put in my test results. CH is steady at 275
