I think you understand now Brett, but I'll make some comments for those people following the thread.
When you add the CaOH (= lime = "kalk")to your freshwater, you can agitate it mechanically to speed up the dissolution of the CaOH. I think this is what the directions meant by "well mixed". This will make a cloudy or "milky" mixture of limewater AND lime solids. Unless you are experienced using lime, you should not add this cloudy mixture to your tank. In approximately 2 hours in a closed container, the water will become clear with lime solids (excess CaOH that did not go into solution) settled at the bottom of the container. Once again, you don't want to agitate this settled solution (put the lime solids back into suspension) unless you are experienced using lime. The clear, saturated solution of limewater is then delivered slowly to the tank.
Delivering milky solutions of limewater is trickier. The advantage is that you are delivering more carbonate and calcium to the tank than with a clear solution. The disadvantage is that this places a higher demand for gas exchange on your system, increasing the risk of a pH spike.
By agitating the mixture, it never settled, and you delivered a tremendous amount of lime solids directly to your system. Gas exchange could not keep up and pH began to rise, causing the stress to the coral and fish that you observed. When the pH and carbonate levels got high enough, calcium carbonate began precipitating out of the tank solution. This caused the "snowstorm" that you saw in your tank the morning after the incident. I'm not sure about the "white chunks" on your rocks, but this could be precipitated calcium carbonate.
With that much lime delivered to your system, I'm suprised your pumps did not seize. This is one of the first places calcium carbonate will precipitate out of the tank water.
I don't have pink stylo to replace the stylo you lost. I've got cream stylo and pink birdsnest and pink poc, though. Also zoos, some montiporas, good old A. youngei, and other odd and ends you may want. I can bring them to a PSAS meeting or you can come here and pick them. Just PM. I would give it a few weeks. Your likely to see a bad nutrient bounce, unfortunately.
