I disagree and have a completely opposite experience.
My Alk started around 7.9dKh and based on recommendations from this forum, I slowly raised my Alk from 7.9dKh to 9.89dKh over a period of about 45 days. In the same time period, I watched my corals bleach....all of them.
After letting my Alk drop back to where I hold it now (~7.5dKh) all of the corals color has returned. All other parameters such as Calcium, pH, Temperature, Nitrate, Phosphate, etc has remained the same.
So based on my experience, your statement cannot be applied as a blanked to all tanks.
