Over months, a saturate solution-with a bit of solids still on the bottom of the bottle---will slowly rise in TDS. Why does it not just go up to point of saturation?

James: Calcium carbonate has very limited solubility in water, so variations in particle size, temperature, dissolved CO2 from the air can all have a very large impact on percentage variations in its RATE of dissolution. Temperature and CO2 also effect the saturation limit of calcium carbonate. So you are probably looking at a "moving target" with regards to RATE OF DISSOLUTION and SOLUBILITY of calcium carbonate.
