I discovered shortly after getting this, that the "saturated" liquid that was being dosed to my tank was losing potency very quickly. The PH of my solution was dropping in PH by 0.1 per day/day and a half. Even knowing that PH isn't really the best way to measure the saturation of the solution, I get consistent readings and it showed it dropping very quickly.
So, I made these 3D printed "paddles" to mount on the stirring "blade" to hopefully agitate the thicker slurry at the bottom and mix it better with the fresh RO water being fed into it. So far, it looks like it's working somewhat. Without me adding any more kalk, the slurry at the bottom rises a bit higher and the fresh water inlet now pushes the freshwater into the slurry. I'll know more in a few days if this actually makes a difference or not. If not, I guess it's back to just using a larger container for fully saturated solution rather than using a stirrer.
Anyway, I thought this might be of interest to some folks here.
This is what the paddle attachments look like:
