lighting spectrum for refugium

[MontanaBay]

Do people light with a more typical freshwater spectrum (reds) if you are growing macro algae in a refuge?

Thanks,

Typically, people use 6700k up to 10,000K bulbs for a fuge. Works well. Treat it like a plant. I believe there was a simple test with 3000k vs 6700k and the 6.7 was noticeably better and promoting chaeto growth.
