Dana Riddle had a interesting talk at MACNA last year on high alkalinity levels and increased photosynthesis in corals. He has a lot of good research on corals growth and coloration.

Good water chemistry, lighting, and flow can make for some great looking corals!

Dana uses pocillopora a lot in his studies. Those things grow like weeds in the worst of circumstances so I am not surprised that they might do good with high alk. I've never found low or high alk to have much impact on growth. Better to keep ca around 450 and Mg 1350-1450.
