    How does cold water temp. affect test results?

    This is my first year using BBB. I let my Cl levels fall, and the water is clear, but green. I didn't drain this year, so when the weather is cold, I run the pump 24/7 , which I want to do to clear up the green anyway. I was just wondering how the cold temps, (37 degrees), might give me inaccurate test results.

    Thanks,

    It is important to allow the water to warm up before doing the CYA test. The chlorine test, on the other hand, should be done right away. If the water sits for any period of time the chlorine levels can drop. The other tests can be done either way, though you will need to mix after each drop for longer than usual when the water is cold.

    Hi, Jenlar,

    Running the pump will not get the green out of your pool.....that will take chlorine and running the pump both.
