How to dose Kalk with dosing pump based of pH probe?

FireEMT · Mar 9, 2017

I have heard thats its possible to dose Kalk based off your pH probe. To write some code saying if pH drops below some value then to dose Kalk from a separate container. Is this something that works. I currently dose 2 part but want to add some Kalk to boost pH to help battle some Dino. Any information would be appreciated.

I definitely would not use a pH probe, except to stop dosing in emergency overdose.

Most people can let it dose close to the evaporation limit without any excessive pH issue.

So your recommendation would be to just add it to the ATO reservoir? My ATO pump sits right on the bottom of my 5 gallon container. How much would I have to raise it off the bottom and how much Kalk should I add each time? Thanks in advance for the information.
