Re: [AGA Member] Red Pigment-K spectrum experiment

["Dennis Sheridan" <dilvish@pacbell.net>]

Hi, Roger!  Got rid of that carbon block co2 dooby. After testing
with both a diy and an injection system, I don't know what the hell
the carbon block was doing, but I couldn't get the tank to behave
like the real co2 systems - in that cranking it up wouldn't affect
pH among other things. So I switched to real co2.  See no difference
in plant growth but my other parameters have definitely improved.
(Having some nice success with an extremely low tech tank now, too.
Nothing but good soil substrate, medium lights, and only weekly 25%
water changes.  That's all the maintainance I do.)

I have some Lobelia that is written up as red under low intensity
lighting..  put one clump in a small tank with low lights and the
upper leaves did turn red  Put it back in the big tank and they
turned green within 48 hours. I have another stem plant whose name
I've forgotten and the leaves in shadow are much redder than those
in the light. Again, the pictures I saw of the plant before I got it
said it was red under low intensity..  But check out the description
of the lobelia cardinalis and you should read what I'm talking
about.  (God, I hope I got the name right.. I'm awful with names.)
