Yours are some good questions. As far as I know, there have been no studies investigating coral morphology and spectrum and I can only relay personal observations I made during my time in Hawaii. Porites corals in shallow tide pools grew in flattened shapes while those in deeper waters were mound-like, which seems contrary to the thought of self-protection from red light. In other corals (Pocillopora damicornis) morphology has been linked to environment - probably water motion.Guys, I hope you don't mind my reviving this thread. I feel the information I am looking for is in here, it is just beyond my ability to understand at this point. So many things in this hobby to try and learn in depth and photosynthesis in coral hasn't been my focus "yet". Is there a practical application from this discussion on the role of red lighting in a reef tank?
For instance, what impact would high levels of red lighting have on coral shape and growth? For instance, would high red lighting encourage corals to stop growing up and start growing out (or down) since it may think it is close to the surface?
Will high amounts of red lighting adversely impact the coloration of some corals more than others?
Thank you Dana.Yours are some good questions.

Interesting observations. Could you share some photos - you definitely have my attention!Thank you Dana.
I am observing a few things in my tank which make me think the red LED's could be a contributor. My green and dark purple monti cap's tend to grow down but my orange monti cap grows in a more traditional manner. That had me wondering if the orange color was reflecting more of the red causing a smaller impact.
My tank also doesn't show much in the way of green corals with the exception of Pocillopora. The green corals tend to turn purple or brown but the red and blue corals hold their colors better.
I have some older photo's (March) handy but I can take some new ones soon. Not the greatest but it does show the shape they are taking.Interesting observations. Could you share some photos - you definitely have my attention!
I will... I have been very tempted to cut way back on my reds because of concerns about coral growth and coloration but I may let it ride another month to collect data. Not to mention that I feel previous lack of success was due to changing light settings too often and my coral never adjusting. Hoping to do a 1 and done when I do make the change. LED's are wonderful... and dangerous for tinkerers.I was talking with Nick at Fluence Bioengineering, and he mention how they build horticultural LEDs to get growth, bushiness, flowering and even sugar content in terrestrial plants. In a very general way, aquatic environments are the opposite of terrestrials (on land, lots of red light equals shade, while it is the opposite in water - red is high light, and blue is deeper or shaded areas. We have a lot of learn. Thanks for sharing the pics - interesting! Would you keep me posted on these corals' growth? Thanks!

When the confusion leads to learning, I'm good with it!I´m just want confuse you more
It is impossible for me to be more confused. But thanks for sharing Lasse!I´m sorry to say - in my aquarium - It is the opposite. This two is situated below the most red part of my aquarium (around 10 cm from the surface) In this part - one of my modules in my fixture are broken and produce less blue that the other modules. There is also around 12 - 15 watt red of 745 nm hitting this part, IMO - the downward growth of the red is rather depended of the intensity than colour. I have seen the same in another aquarium with high intensity (and a lot of red)
I´m just want confuse you a little bit more

Yes, agreed. Constant tinkering with lighting is probably not beneficial for photosynthetic organisms. Please keep us posted!I will...

When I do make the change I can continue to track the growth and see if it changes from the current almost plating they do now to more of the cupping.
