    testing cold water

    Found in a post that CYA should be measured at room temp or higher.
    My water is 42 degrees upon opening.

    CYA measure artificially high or low that cold?
    How about testing FC/CC/pH/TA, etc. at this temp?
    Reliable?

    Thanks!!

    The only test that;s normally affected by cold water is the CYA test and it can read low if the water is very cold. We usually recommend running all the other tests and letting the water warm up before running the CYA test.
