And I love a good debate! Thanks guys.
I agree and the rest of the readers may have picked up more info from both sides. Just a quick note though. You often refer to PAR when we know that PUR is responsible for photosynthesis for corals. PAR is a broad term for all photosynthetic life which includes wide range of colors while PUR is specific.
I believe a color temp that works for one coral, will work for all corals. You just need to turn up or down the intensity.
