You're right, they add supplemental lighting to it, but it sounds brilliant. Why not use the sun if you can regulate and enhance it?

I can see myself starting a reef out in the ocean and growing out frags in the aquarium and then moving them out to the ocean reef to grow. Now just to get my money trees producing first....

Speaking of the sun...Check this out!
I was sitting on a lounge chair in my back yard, and feeling the hot sun beating on my bald head, I decided to whip out the PAR meter.
Check out what the sun is hitting my back yard with-


And even indirect light (notice the probe pointing at my jeans)

That's why I started the experiment with a super bright LED on a moving rail system. I hit my acros with +1200 PAR for several minutes out of each hour. Not enough to burn them, but it does cause exceptionally dense growth.

Dense? Don't you think density, or the thickness of the branches to be attributed to flow? How was the coloration?

As said, it's an experiment. I meant to imply the branching is closer together than what I see under more conventional lighting. Flow is kept high because of the light intensity, but as you were implying, that also has had an effect on the growth pattern. Coloration is great. Purple acro is purple with blue tips, etc.

I couldn't get the pictures to open up. What wre the values you measured? My meter shows almost 2000 PAR in noon day sun.

What would you guess that translates to on the equator under 10' of seawater?
