I am curious to know what method people use to dose Kalk? I have been using Kent 2-Part but that is getting way to expensive at the rate I am dosing. I have tried dosing Kalk using my auto-off system in the past but I didn't like the results, to much potntial for an overdose.
I was considering using a drip can like this:

Any ideas or suggestions would be great.
