Hello,

Does water temperature affect the FC or CC test? I opened my pool and the water temp is 57 degrees. If I test FC and CC as soon as I take the water sample will it read differently than if I let it sit inside and warm up to room temperature?

Thank you.

Thank you very much. I believe I found what my problem was. My FC reagent must of gone bad. Might have been 2 or 3 years old and when I used it, it showed I had very little chlorine despite clear water, and CC of 0. This was despite pouring many gallons of bleach into my pool. I used new FC reagent from my Troublefree Test Kit and showed I had FC of 30!!! I tested it twice and came up with 30 both times. Now I know it was not the water temperature but the reagent.
