thank you for taking the time to reply.

would i be very far out if i started off with a blank sheet and zero all of the boxes in Water tab?

Yes! With a very low TDS of only 8 ppm, you can safely just begin from the assumption of zero mineralization.

My initial and purely ballpark guess is that your RO water has no higher than 3.15 ppm Sodium ion and no higher than 4.79 ppm Chloride ion, and perhaps about 0.08 ppm Alkalinity. That particular combo hits ~8.0 ppm TDS, and also balances cations and anions at 0.137 mEq/L each. Albeit that other combos may do likewise. This assumption presumes that your water passes first through a water softener, and then through an RO unit. If it doesn't, then all bets are off as to such guessing, with the caveat that it doesn't matter and you can presume zero mineralization.

That plus 35/23 x 3.15 = 4.79
(whereby the MW of Na is 23 and the MW of Cl is 35)

Thank you for that, I don't have a water softener.
