high alk

[jared graves]

Is it true that if your alk is too high the skeleton of some sps corals with actually outgrow the flesh?

I believe this is true in very low nutrient system. Maybe @Randy Holmes-Farley can chime in with a more specific answer.

It is a hypothesis that it can happen in ultra low nutrient systems (causing burnt tips), but it doesn't seem to be an issue in higher nutrient systems where both the skeleton and the tissue can grow faster.
