Dimmable full spectrum setting

[lullaby2paralyze]

I am trying to search google for recommendations on what percentage to keep my lights at but cannot find anything.

I only have one piece of coral and a few fish right now (watchman clown and chromie) and clean up crew as my fishless cycle finished recently. I just want to make sure im giving enough\not to much light.

I dont have a name for the coral but here is the pic

Thanks.

Most would put it like 60% blue and 30-40% white. But its really up to you and what your lighting taste is.

Thank you for your response. Thats about what I have it at so thats a good thing.

We are doing a lot of research on the subject.

The bottom line is your 420-460nm is your primary grow. The Cree and Luxion Cool White have this in their spectrum.

Too much Red has been shown to inhibit coral growth. Along with promoting some Macro and nuisance algae. However a little but not too much Red helps the looks of some corals.

Corals are highly adaptable and develop pigments to reflect and refract different spectrums of light.

Photohinibition starts around 350-500PAR depending on the species.

Its always good to slowly acclimate your corals to this with a max photo period of 4-6 hours at the top of your tank.

Then add just enough of the tertiary colours for optimal looks. Every tank and every eye is different.

Corals will appreciate a more natural high level of light if properly acclimated.

This is the part thats art. Start slowly, ensure that your corals are growing then once you have a solid foundation slowly tweak for looks.
