I have gotten a Kalk Stirrer from Avast Marine Set it up and have it working, been running about two weeks now and i am starting to see the PH drop, does that mean that the Kalk is depleted even though there looks to be lots of Kalk Median remaining? It is winter here and it is a little colder, so my evaporation is a little less, but the temps have been this way for more than the time the stirrer has been running, and i use heavy duty heaters and chiller, temp swing is only .3 to .4 of a temp swing.
