Thanks

TDS = total dissolved solids
To the best of my knowledge, this is a measurement of all solids dissolved into molecular form in the water column.

KH = carbonate hardness
This is a measure of the dissolved carbon molecules in the water column.

TDS might include carbon in its measurement, but also includes other things. KH is very specific to measuring carbon only.

+1 to above.

TDS measures the level of all total dissolved solids in the water. There is no direct relationship between that and KH. Which higher TDS COULD possibly mean higher KH, that's not always the case, as more TDS could mean more dissolved solids of another kind, and KH could be unaffected

Hope that helps.

This might help a bit. (hint,,, KH is not a carbon count)

TDS measurement can't replace knowing KH values in my opinion.
