    Default Air bubbles in reagent bottle

    Hi.
    On Saturday I intalled KHD.
    First test 14dkh. (Normal, the reagent was not in the end of the tube inside KHD)
    2º test. 7.4 (10 min later)
    3º test. 7.4 (2 hrs later)
    Tritation test says 7.5
    I increased the carbonate amount a little. (From 8 times a day to 12 times)
    24 hrs later I observed air bubbles in the bottle, not in the tubes.
    4º test. 7.2
    5º test. 7.2 (20 min later)
    The system can manage my carbonate feeder to increase or decrease the times it drops carbonate, great product. But, those bubbles are a problem?

    The micro bubbles are a reaction to the ambient temperature. This is not a problem because the bubble seem to be only stuck to the upper parts of the bottle and your test results are within the acceptable tolerances. If the bubbles were really a problem, you would be seeing much larger test variances.
