Interesting, I have liquid rock with a TDS of 300 or so pH 8.3
That is hardly "liquid rock." Cute term but wildly abused, IMO. 300 ppm,
*if* it carried the usual US 200 ppm of CaCO3 equiv. hardness, would be
on the borderline between moderate and hard water, and hardly rock-like.
The GH is 0 the KH 180ppm, or 10 degrees german hardness. Calcium is
only at 20ppm, I am not quite sure what is buffering my water but it
isn't calcium.
In many parts of the country, sodium carbonate/bicarbonate is the active
buffer, contributing nothing at all to the hardness. Sounds like you
live over a soda spring. :-)
It is well water from a 420ft deep well. One day I'll
fork out for a full analysis.
If the Ca is 20 ppm, the GH is at least 1, and likely a bit more. You
may want to question the accuracy of your test kits.
So by your reckoning Low calcium = Low TDS, not quite true with my
water.
No. Hard water (high Ca/Mg) is also always high tds, but the converse is
sometimes not true. Natural soda springs are one obvious case in point.
Please correct me if I'm wrong ;)
Did that, I think. ;-)
