I'm tired of having Kalk in my ATO reservoir and am thinking about getting a Kalk stirrer. I looked around today and seems that there are2 types. The stirring wand and the up flow. Any opinions?

I run a dosing pump and use a timer on a small air pump and bubble a few minutes a day at a slow bubble rate to keep it mixed. I now run slow bubbles in all my dose bottles for 15 minutes several times a day. I use the smallest air pump I could find and a bank of air valves. I dose five products.
