I was under the impression that spectral changes occur in the oceans’ reefs as the sun rises, peaks, and sets. I mainly thought this was the case due to the atmospheric shift in color during sunrise and set. After watching a few in-depth BRS videos and reading some older articles from Orphek, I’m not so sure I understood this topic entirely anymore - does the water absorb most light leaving a constant spectrum for the reefs inhabitants regardless of spectral shifts above the air-water interface?
I currently run my AI prime light on a modified Saxby setting (lower cool white lighting due to my small tank size). BRS and Orphek have both stated that the spectrum should stay the same throughout the day and Orphek goes on to state that lighting spectrum does not change in natural reefs, just intensity. I’ve gone down a rabbit hole and have become more confused. Here is my lighting schedule for reference (corals started to bleach on me about a month ago, I lowered my intensity and adjusted the spectrum slightly which has led to some stabilizations in coral health - some tissue recovery but no significant growth)
