Lead,
Structurally my tank still looks about the same as in the previous photos. The main difference is in the algae growth... no cyano, lots more coralline, more macros of various flavors, and some annoying hair algae (hasn't choked anything). If you're expecting some conclusions about coral growth, I think you'll have to wait another year -- and my tank isn't a good test bed anway if you're interested in Acropora or other very bright light species (can't get Caribbean species and I don't think my light is that bright anyway).
I agree with your comments about algae growth except I don't know if I believe the bit about red light. Everything I've seen about spectral effects on algae seem to be anecdotal. Do you have any references to controlled studies? In any case, I don't know why sunlight would foster algae growth more than the 6500K bulbs that many people use. The average color temperature is about the same.
If you want to filter out the red, I suggest getting a photographic filter of the sort that fits over a lamp and converts "tungsten" to "daylight". B&H sells a 4'x24' roll of Rosco Tungsten Conversion Filter (in various densities) for $106.95. In practice, however, I don't find the light is so bright that I want to lose any of it.
As for yellow water... I think that's a water management issue, not a lighting problem. Blue light may mask yellow water but won't prevent it.
