    I did some testing with my API test kits and found these readings. If someone could respond to the results that would be great. Not sure if a couple of the readings are out of whack or not, and if so, what the remedy is. I do not use R/O water and my tanks have been running for about 3 months now....
    any help would be great.....thank you in advance.

    GH over 214 ppm kh/gh (my chart does not go higher then this. I am a little concerned about this reading, not sure if this is normal.
    KH about 6degrees or 107.4 ppm kg/gh
    N03 about 10mg/l
    NO2 0mg/l
    ammonia 0mg/l
    tds level 270ppm
    ph is about 7.8 (little high but that is what comes out of the tap)

    Have you CALIBRATED the test kits against a KNOWN reference solution?

    In other words, you should have a known sample of water at say 10ppm of N. If your test kit shows the same level, you are good to go. If not, you have issues.

    If not, this could result in FALSE/misleading readings.

    Every test kit, whether the cost is $1 or $10,000 should be calibrated.

    Hobbyist test kits are not as reliable or accurate as we would like.

    If they have not been calibrated, then I would NOT trust the results.

    Hope this helps.
