Need advice taking pictures with LED`s

I have read that depth is the key. I have read that In the ocean only great clear light reaches more then 3 feet in depth and that's why many pictures come out blue in some reef shots. Because the blue light reaches great depth. I don't know what that depth is for sure. It depends on the water I think and other factors.  I think also depends on your lighting. Try taking pictures right up at top and see if what I have read proves out. Just a suggestion and not sure if it plays out like this in our aquariums. I find it very hard to take pictures with Actinic on where the best color is on our corals. I am getting better.
