I've been running kalk in my ATO for a couple months now. Manually adding calcium, alk and mag. I finally have my numbers where I want them. I just got a dosing pump and am trying to figure out my numbers. My question is, should I stop running kalk in my ATO? Kalk seems good but because its added with evaporation, would it be more accurate to go back to Rodi and dose with an auto dosing pump. Seems if I go back to Rodi I'm taking one variable and possibility for error out of the equation. Thanks.
