I'm running a 240 gallon tank (350 gallon system) using a calcium reactor. I have reasonably stable alk and calc, but have decided to start using kalk instead of the carx, and I'll bring the carx back online if and when my consumption exceeds what I can add each day with the kalk.
What I'm thinking I'll do is to figure out my daily evaporation rate to set as a max ceiling for the amount of kalkwasser I can add each day. Then I'll start dosing kalkwasser using a dosing pump connected to my GHL controller. I'll monitor my PH, and stop dosing if it ever gets too high at any point. What I'm not sure of is how to figure out how much kalk I should dose each day. I'd like to continue to keep my alk and calc levels steady as I transition to kalk. Should I measure my carx effluent to figure out my daily consumption? If so, should I go by the calcium, or the alkalinity level in the effluent?
