I know from scuba diving that in the ROYGBIV light spectrum, that the blue & violet parts of the light spectrum will penetrate the water column farther than the red & orange parts of the light spectrum.
Question: My friend told me that (in general) that either the red, orange, yellow corals sit at the upper most of the water column or the BIV ones. I would think that since the blue, indigo & violet parts penetrate farther, that if you want to make a generalization, then red cousins would sit higher than blue cousins of the same species.
I have a nice Ricordea Florida with purple in the center, orange circle around that and a small green ring around the outside. It sits about 9 inches below the surface and there are 2 inches of air between the new HO T5 bulbs and the surface of the water. It's doing VERY well so far. The T5s are producing 1200-1300 PAR (2 whites/2 blues) right below the fixture and 1100 at 6 inches.
I just bought a new Ricordea Yuma with a white center, pink around that and yellow on the outer rim. It's a Ricordea so I thought it needed moderate to heavy light, but it seems washed out at 9 inches below the water surface. I gave it 2 days at the bottom before moving it up. Should a lighter color Ricordea sit lower in the water column or higher? Does placement in the water column different for Ricordea Floridas versus Ricordea Yumas??
