OK so I will probably going with a soft-sided above ground pool of some sort this summer
Now I need to decide what to fill it with.
We have a high-flow well that draws what can be considered an aquifer with near unlimited supply. That would be great except for that the well water is ultra hard and kind of crappy. And the pump has to lift the water 50 feet up a hill to get to the pool site, so the flow rate isn't that impressive up there.
The pH is pretty good. It is 7.
The carbonate hardness (I believe you are referring to this as calcium hardness here) is off the charts on any test kit I have tried. If the water is boiled, it will form a large amount of calcium carbonate precipitate.
The general hardness is obviously also off the charts.
The water is moderately tinted with tannins (green/brown) and contains 300ppm of nitrates because it was drilled below the cattle yard (previous owners ). The colour will bleach out, though, and the nitrates are fine if you don't actively drink the water.
So, does carbonate (calcium) hardness affect a soft-sided pool much? Will it feel crappy to swim in, as bathing in the raw well water often leaves your skin feeling, well, anyone who lives in a hard water area knows.
