So there's two different types of carbon? You're loosing me here Nick :)

Certainly more intense, but I'm not sure about them being any different.

They would look yellow next to a 10k, if the 10k were considered "the
standard". However, I look at the "looking glass" differently. I think a
10k looks too blue next to the new generation 5500k or 6500k because I set
my baseline at what things look like under the sun to my eyes. Since my
sinuses suck and I can't go more than 8 feet under water, I've never had the
experience of seeing a blue light natural system. It's all about
preferences and scope, and I'm not sure why we're spending time debating a
"taste" issue :)
> Were you a reefer...
Yes, yes and yes... In fact I was still using the 6500k prior to the DL
enhancement _in spite_ of 10, 12, 14 and 20k solutions (for reasons of PAR
output), had talked to Sanjay in person about this before and during the
time he ran these tests, etc. I would say the most fair treatment of these
data would be in context (including which ballast was driving them) and can
be found on the Advanced Aquarist Magazine website or, if it exists still,
somewhere in the pages of Aquarium Frontiers (which I think he was only
looking at 400 watt at that time). I'm sure that Shane Graber could chime
in volumes of information about all of this as well, has probably talked to
Sanjay in much greater detail than I have, because, well, Shane is going to
hold Sanjay's attention longer just because they're two peas in a pod and
I'm one of those arrogant biology geeks who just wants the basics of the
physics, and I'm off to the next big thing :)
So to draw this back to what my question really was... rhetorical question
that it was lol
There are tannins in my system. Is the source the wood? Is the source
80lbs of potting soil?
As I turn my focus away from killing wee beasties with a water change
tonight... I will begin to dissect the question and arrive at a solution to
My lights are preferential. It's just really danged convenient that they
cost $65 less per bulb ;)
