corals are sensitive to rapid and wide changes in water parameters whether it be temperature, pH, alkalinity. Due to the how large the volume of water that is in the ocean these parameters really don't fluctuate as much as you would think besides temperature. pH only dictates how fast coral can grow but corals are much more sensitive to changes in temperature and alkalinity.

pH does not fluctuate much, true, but it drops steadily which is just as deadly to coral.
