I've noticed that my pink goniopora is not happy when photosynthesis is at it's peak later on in the day. This light peak also corresponds with a peak ph around 8.3 to 8.4. this seems to be the only coral affected by the higher pH. When the oh is low early on in the day when the light is just starting to ramp up the goniopora seems to be happiest. Has anyone else experienced this or have any insight into this?
