Total Hardness or Total Alkalinity to Bicarbonate

[mwayne112]

Can anyone help me convert to HCO3? Water report has a range for each of the flavor minerals, hence the two rows.

Ca​	Mg​	Na​	SO4​	Cl​	Total Hardness​	Total Alk​
16.40​	0.00​	1.70​	26.40​	4.22​	52.00​	28.00​
18.70​	0.00​	1.86​	29.50​	4.47​	72.00​	32.00​

34.2 to 39 ppm as bicarbonate. But you have a far larger problem, as the figures given can not be made to achieve cation/anion balance, so thereby they can not be correct.

Bumping the Ca to 25ppm balances it, right?

Given the Total Hardness values, some Ca and/or some Mg hasn't been accounted for. And 0.00 Mg is pretty suspect, so I'd guess Mg is the issue.

Your magnesium is on the order of ballpark 4 ppm.
