Light spectrums and coral coloration

[Raphael Dalmeida]

Hi guys,

I've read the following article:

Coral Color Management｜BlueHarbor

This is a coral color management theory created by scientifically understanding the color of coral from an optical perspective.

www.blueharbor.co.jp

And as much as I understood the principle I'd like to confirm with the more knowledgeable people here in the forum.

Currently I have 4 pop bloom lights that are very similar spectrum to the Red Sea 90 leds. It's a huge amount of Blue light, and a bit of Cyan, White and Moonlight.

Based on what I've read on this article, to better excite RFP, BFP and YFP and chromo proteins certain spectrums and intensity are required.

So I'm wondering if it would be beneficial to supplement my lighting with additional LEDs on

UV 395-400nm,
Green and Cyan spectrums
and Amber light through Warm White Light (3000-4500k).

As much as my corals are growing and doing well, I feel like the coloration is not quite there.

Help me out here hehe I'm no expert.

Thanks for sharing that article.

I know I'm running full spectrum, to 3-hour ramp up that starts with blue and ends with a very white light for 6 hours and then it ramps down opposite of ramping up.

This is what my peek looks like;



It's like I need more green myself.
I'm just going to follow along for now.

There's a good chance that would help with coloration, yes, but I can't say for sure if it would.

To add what I can here:

For that reason, like I've said before, at this point in time (barring a major, undeniable scientific breakthrough with our knowledge of corals and light), I would personally only suggest running the windex blue tanks if you really want to see the coral fluorescence pop (as mentioned by others, though, the colors may be best in the long run if you run different spectrums than just blue throughout the day). Like many others have mentioned in various forms by this point, I'd personally run a full-spectrum (white) light that leans somewhat more toward the blue side of things. Is that the "best" spectrum? Maybe, maybe not, but it seems like a good, safe place to start from.

Colours of corals

In the thread https://www.reef2reef.com/threads/have-we-been-wrong-in-our-understanding-of-par-this-whole-time.1035018/ all from PAR to coral colourations is discussed. Among other things - coral colouration during different wavelengths was discussed. I decide to start an own thread according...
