RE: Plant ID's and Lighting
I think the following bounced on my end the first time I sent it, so forgive me
if you've already seen it...

Thanks Karen. I'll check the books I have for this possibility when I get
home. I've got both Baensch atlases and the Rataj/Horeman book. I'll see if I
can't find a species in those books that resembles what I have. Maybe that'll
help a little more...

Oops. I didn't mean to imply that I haven't seen _any_ T8 bulbs for plants. I
just haven't seen any in the 48" length that I need. The largest ones I've
seen are 36". What I have now are Sylvania Octrons, 4100K. They replaced two
15w Tritons (see below), so the tank went from a pleasantly subdued blueish
tint to garrishly bright green. I've gotten used to it now, but I'd still like
to "soften" the color a little.

Fortunately, I didn't have the need to do any retro-fitting. The fixture I
bought is a single, self-contained unit, including (I assume) the starter and
ballasts. The hood that came with the tank had two 24" fixtures, which held
two 15w Tritons. However, I didn't figure 30w of lighting was going to be
enough over a 55 <g>. So all I did was remove the two 24" fixtures and simply
replaced them with the new fixture, which stretches the entire length of the
tank. Now if I can just find another one like it I'll really be in business as
far as adequate lighting goes...

I'm in the process of checking out the more commercial lighting places here in
Atlanta. I'm also actively searching the net for web pages of flourescent
lighting places. You've got me convinced I made a pretty good purchase,
