Are the seas really calmer at night?

I did not realize that the photo cell addition could have caused it till i looked back in my journal and did some reading.

maybe its just the change that caused the decline. IME, when there's a sudden change of something it usually caused a slight decline in my corals but after a few days, they adapt and continues to thrive. How long was the tri-color positioned at the highest flow area before the change? Did it completely bleach or did it come back after awhile?
