Coralline loves sunlight

Preaching to the choir for the most part, but cool to see it live in action. Accidental experiment, did not make time to clean glass for a couple months, and the side of the tank facing the window is speckled with coralline while the other side has only a few small blotches. Neat.

It definitely favors a “daylight” spectrum with higher whites compared to our “bluer” tanks. I found MH builds I had in the past grew coraline way faster then the radions I switched to. It’ll still grow very well under LED’s but nothing compares to the sun.

Depends on the species in terms of wavelength. I recommend reading ARC's literature on the subject as this is their wheelhouse (specialty).

If coralline really does prefer whiter light, that may be why it grows so well in my white lit tank.

Beautiful! What lights do you run? Is that at 12000k?

I have three AI freshwater blades and one AI coral glow blade. I think it is warmer than 12k. The picture is an unfiltered iPhone. I try to mimic shallow water, including the uv end of things.
