Anyone use LED to make acros "pop"

Yes I saw yours and it looks great! Do you notice a difference between the natural whites and the cool whites? I think mine are slightly yellow and I might swap them out for a 50/50 of white and blue. I wish I had a PAR meter but I think the #'s would be close to yours. I have all my SPS on the upper half of the tank and they seem to be coloring well.

On that led strip, I have 2 natural whites, 4 cool whites and 6 royal blues. So as a whole those natural whites do not cause much different. But looking at it individually, nw is warmer than those cw. I was just experimenting and left it as was without changing back to cw. (As you might know, it is a lot of work to replace LEDs in this DIY strip )

OP, please excuse me, I was a bit sid-tracked.
