Do you by any chance have a spectrum graph of the reefbrite XHO?

WOW. Thanks for this graph. So which one of these is more beneficial for corals and colors. Assuming that orphek will give you more POP?

It depends. There are several hundred fluorescent proteins and the spectrum that excites fluorescence varies. I wrote an article some years ago that looks at excitation and emission spectra of corals and anemones. See here:

No, but let me see if I can track this down.
