Montipora plating coral

[reisy00]

I have had this coral for several months and it's growing like crazy. Last night I reaquascaped and added an extra power head in back of tank. The montipora remained in same spot only difference is the flow. Woke up this morning and several white spots on my monti. Any suggestion? To much flow?

I personally dont think so. The only time I've ever had coloring issues on my red cap or green cap is when calcium gets low. What is your calcium reading?
