Auto top off and kalk dispenser

I have the same Tunze setup. I like it a lot. I am using it on a fresh setup now but when it was on salt I thought the kalk reactor was pretty good. I had to shake it pretty regularly to prevent caking though as it does not have a stirrer. But it was nice, especially the the infra red sensor for the topoff. That is a very low maintenance item. I cleaned it maybe twice a year.

 

Thank you for the look for. Looking at the bottom of the dispenser, I noticed the transfer point is pointed down toward the bottom of the dispenser. Am I right that this would stir the kalk during each top off cycle, thus minimizing the caking problem and keeping suspension going?
