do you mind to share this info, and background, to bad for that knowledge to stay wihit you, while you could share !!
For you Kevin, ill share. But you must understand im not an expert on what im about to talk about, ive just been really sticking my nose in books, articles, studies to get the information I need.


There is alot of science behind plants/corals growth. They have what is called chlorophyll A and Chlorophyll B. There is much more A than B but there both important.

A peeks at 425ish 453ish and 660ish. B peeks at 455 and 660.
The LEDs we bring in are the Royal Blue which peeks @ 455. This is great. We also now have an ultra violet that peeks at 425. Again, amazing for the corals/plants.

What we currently don't have is something that peeks at 660. We are working with a manufacturer to bring in a 455 + 660 LED. This would be an LED that is mixed, which is also called magenta. So very pink, not super nice to look at but in theory should make corals go crazy - Similar to a fat kid in a candy store.

What im going to be testing is running these magenta LEDs when I am not home. Basically right in the middle of the day so the corals can color up and grow. Before I get home, they would be off so you see the nice pleasant 14k look. In the future I may also add a motion sensor to have the magenta LEDs shut off is someone is near by the tank.

So what everyone has been doing works great. Royal Blue and Cool Whites are really popping corals, making them grow, etc. What im going to try to do is take it to the next level and see if I can get the correct mix of Royal Blue and 660red for "off hours" to make the corals pop even more and grow even faster.

Here is the activation spectrum im talking about:


It is the mix of A and B.
So as you can see, having the ability to "dial in" the LEDs is a huge bonus over other lighting.
