I am dosing Calcium, Alk and Magnesium with a 2 part dosing system and an automated doser. I am testing for the above as well as phosphates (which are not measurable in my system anymore) and occasionally nitrates. My controller also measures PH. I do have pretty low nitrates but am getting some algae growth so I added bio-pellets. All other parameters are right in the range of the above mentioned article which I often consult.

What is KH and how does it interact with Alk and PH? I am having a hard time finding any info on KH specifically.

Unit of alkalinity (alk) is dKH (degree of Carbon hardness), measured in dKH or ppm. Hope that clears up the confusion. If you are measuring alk (since you are dosing the big three), then you are measuing dKH.
