It would be easy to increase the mix time or frequency if I wanted to (via the Aquatronica). 10 minutes every 2 hours seems like way too often to me. As I watched the stir action, 7 seconds was about as long as it took to make milk up to about 2/3 height in the cylinder.

I figure that by keeping it at 7 seconds, a few good things happen:
1) I avoid running Kalk powder through the pump
2) The pump doesn't have time to heat up.
3) The remaining undissolved solids settle to the bottom more quickly, ensuring that I only deliver clear Kalk to the tank.

I figure these will help avoid calcification inside the pump, and possible precipitation at the delivery point in the sump.

The un-answered question is whether the quality of my saturated liquid Kalk diminishes between mixing. I'll watch that. It could be possible that I may need to mix more often as I pump more water through the reactor. Even then, I'll be mixing more often, but not longer each time.
