FWIW, Dana's observations are consistent (~350mmol) with this study done in situ at heron island, GBR.

I will list references I have come across in my search as to avoid duplication. I will keep this updated:

I think the "What in neptune's world?" monthly quiz should have a reward... some of those are really hard and it increases everyone's knowledge of our hobby.
For a current science class I am taking in college, I have the opportunity to write a paper on the denitrification cycle of the captive reef sandbed. Does anyone have any links or files regarding studies or hard facts in this arena? Any help would be greatly appreciated. I will post the paper...
This is absolutely untrue. UV light is well know to be outside of the PAR (photosynthetic available radiation) range, and as brandon stated, is actually damaging in most cases.
ahhh, great lakes... got on the airplane in sunny san digo and stepped off in chicago in January... talk about a shock! I didn't know what I was in for until we were marching around the base in "chill condition 5".
the problem is that your movies need to be encoded as MPEG layer 2 (".mpg" files). You need a good DVD "authoring software that will first convert, then burn the movies to disc.
If you think that setup is "too" blue, I would recommend going with all 14K bulbs, or 10K + actinic. Some people go with the 10K's without any actinic supplementation so that is an option as well.
I've used many different manufacturer's actinics (including coralife currently) in both NO and CF flavors... as long as they output around 420nm you're getting what you need.
