Also, how do you define LEDs as being "brighter". What meter did you use? Is it calibrated for LEDs? The problem is that the primary meter on the market is an Apogee, and that particular manufacturer in no way envisioned the advent of LEDs and has built their meters using a smoothing algorithm that anticipates sunlight or fluorescent light. LED light is not properly measured. Plus we have little knowledge on what happens when we flood corals with specific wavelengths instead of a broad spectrum of wavelengths.

My primary point here is that I feel like you are making comments with a sense of authority that are in no way yet explained in scientific literature. You may very well be right, but I remain doubtful.



Now as to the OP

My tank has varied from 12 to 5 dKH and the color did not change. I do believe that stable alkalinity is a key to colorful coral, but raising alkalinity above that which exists in nature does not change the color of coral of that I am sure.

P.S. My tank . . .
