    Need help. Did some measurement just now for my tank.
    PH = 6.6 ph,
    KH = 160ppm (high?), not sure if I am correct, but I converted to dkh = 160/17.8 = 9?
    co2 = from this, http://www.thekrib.com/Plants/CO2/kh-ph-co2-chart.html
    it is way off the chart. > 30 ppm.

    Meaning that my shrimps should not be alive. but they are, happily.

    Is something wrong? I suspect that my kh test kit is not accurate.

    PS. My tank gets regular treatment of catappa leaves. Not sure if that will invalidate the calculation.

    The leaves you added had caused the KH reading to be inacurate. You will have higher than actual reading for KH and CO2.

    Agak-agak (meaning approximation for those non-Singaporean out there ) can lah. As long as the fishes and shrimps don't complain by gasping at the surface, it should be fine.
