I know but I just wanted CaCO3 equivalents clarified. And now I will have to clarify this CaCO3 equivalents
This is really not a REAL value. It is an expression conversion and the value does not really give you a true value of how much Ca++ there is.
It goes like this. IF water could hold 150 ppm CaCO3, which it absolutely can not, it would yield a concentration of 150 ppm CaCO3 if all the CO3-- was attached to a Ca++ ion. It is a poor expression from long about that gave the "potential" of you much CaCO3 could leave solution. Be it FW or SW only a very small amount of CaCO3 can held in solution. It is only a few ppm. Remember here we are talking about CaCO3 in solution and NOT Ca++ and CO3-- in solution. The Ksp in FW is only 8.3 and vs the Ksp for Kalk which is 5 and something like KCl is 0.98. The lower the # the more it can hold. Dolomite is like 15
