thats kind of surprising. I was always under the impression that red light was filtered out of water so quickly that t wouldnt be able to affect the corals, let alone affect them negatively. Makes you wonder about all the commercially available LED fixtures with red LEDs on them.

I think the red is more to show certain colours than for growth on most of the more commercialy popular fixtures (GHL, AI and Radion). The ratio of red to other colors is pretty low and most programs that use them generally have very little added unless it's sunrise/sunset from what I've seen.

Indeed in the commercial high end fixture red is usually a minimum of the color LED's included .. I think the author just wanted to point out that too much red is not beneficial and can cause damage to the corals.
Thanks for your observations ..
See you soon ( a few days now )
