I warmed up my test sample from 54 degrees to room temp. It took an hour for CYA. Can I test FC, Alkalinity and PH with a 54 degree sample or should I warm that up also to room temp, but that takes an hour and I read that the reading could change
Just measure the sample, add reagent and cap the bottle. Then cup the sample bottle in the palm of your hand and shake it for 30 seconds. The small size of the sample combined with the heat from your hand can easily have it up to temp in the time it takes to mix it.
