Is there a low range temp that might influence the test water for best/accurate results?
I have the ColorQ, and at least the CYA should have the water to be between 70 and 80 according to LaMotte for their tester.
Any such cold water issues for CL, Ph, Alk, etc. that you know of?
I don't "close" the pool as such, just run the safety cover back once a week to brush and test the water.
Anal, I know.
My first winter.
My current water temp is about 42, the FC is only dropping about 1/2 point per week, from 4.30 to about 3.80 (CYA of about 30 taken into account). This seems a minor drop to me.
But then, I was wondering if the colder water was messing up my readings somehow, hence the question.
