Coral Response to certain LED colors

[Badboyan93l]

Hey Refees,

I've been using kessils 3 x160 and 3 a360X together for the past year and I notice every time I adjust the "violets", colors don't mind it. But when I start adjusting the "reds", the corals in a just few minutes will puff up and extend really really really good like the YTbers..... :thinking-face:

PS I have not adjust nothing else....

Probably depends on what you are running the red lights at normally?

Corals (and or their symbiotes) can use red light so if they are "starved" for it regularly, then maybe boosting reds is causing a reaction?
