Would a change in water temp cause a change in the CYA test readings?
I checked my CYA last week when the weather and water temp was warmer - in the 80-85 degree range and it was reading 70ppm. We had some cooler weather with rain come through so I checked everything again and the CYA yesterday and it is now showing 50ppm with the water temp dropped back to the lower 70's. I suppose it's possible my initial reading could have been off since I was just learning to use this new test kit but I want to be sure the temp doesn't have anything to do with it before I add any CYA to the pool because otherwise everything is perfect.
