Thanks Logan. I stand corrected... more or less. Although I guess it depends a bit on whose graph you look at. These show the Chlorophyll a using spectrum out beyond the 450nm that your graph showed. It's not a huge difference, but with the specific wavelenghts we get with leds, it can have an influence. And I had never heard the percentage split between Chlorophyll a and c before, thanks for sharing that. Very interesting.
Here are a couple of graphs with other chemicals that can play a role. Ignor the Chlorophyll b as coral doesn't have any.

Ron, chlorophyll b is not present in coral tissues, you are looking at the wrong plot. That was not my graph, it is available on the internet. Look at chlorophyll a in the graphs above, the peak is at 430nm.

I know that wasn't your graph. LOL!
And I agree, you are right about the peak being at about 430nm. I'm looking at the 'a' graph and the bottom of that peak is at 500nm, the graph you showed had a solid bottom at 450nm. I understand the area between 450nm and 500nm, under these graphs isn't a lot, but they do show some for a little 450nm to 500nm light. I'm not disagreeing with you. Just saying some graphs look a bit different. And I appreciate your pushing me to learn. Thanks.

I'm learning about LED's and one of them is by ORPHEK v2

On youtube, he's saying the opposite about Chlorophyll. Can you guys why the differences of opinions ?

I don't know why, but the last few days I can not paste a link here or even information from my email or from other websites, and it's ******* me off. So please do a search on youtube with,

One is- "Reef-a-Palooza".

I think the other is from MACNA.

I would appreciate you time and views.

Can we see some before and after pictures of SPS coral growth? It seems like looking for a needle in a haystack.

That's what it seems like with theses threads. Everyone is posting how great these are but no one is posting any before or after pics. I just looked through thread that was around 40 pages and I grew weary trying to find any pics of any tanks.
