I think I might make this required reading for our forum! 
Randy's excellent article, which will be a series, on Photosynthesis in the Reef Aquarium, is posted to this month's Reef Keeping magazine. He covers carbon sources (ding ding ding!) this time around.
By now I'm sure many of you have seen it, but I wanted to be sure we've especially noted this one part:
"Of course, the photosynthesis rate does not necessarily translate to growth rates. If other nutrients are limiting growth (nitrogen, phosphorus, iron, etc.), then it may not matter if the rate of photosynthesis is reduced at higher pH. But because these nutrients are often present in surplus in reef aquaria, it may well be that carbon uptake is limiting in some cases, and in those cases aquarists might benefit from ensuring that the pH is not too high."
His table of relative photosynthetic rates of macroalgae at two different pH levels that follows might be of interest as well.
Randy, bravo.
