Of course you are indubitably right, but the point I am making is that FULL SPECTRUM light contains that blue light it is just that the rest of the spectrum is NOT being filtered out by the water. Thus the conclusion I have come to is that blue supplementation is not required for the health of the corals. It just pleases our eyes.
