Well lab experiments are not bad. We have the natural data. Some field
treatments. But ***what is the question*** we are trying to answer? Do we
care about large lakes or ponds? I'd like one, don't get wrong, but not in
my house. I'd prefer a nice stream there:)

Well folks have asked questions about it and I _always_ get asked these
questions that seem to conflict with it. I agree with much of it. I don't
get say what I feel about it overall.

Well I'll say I think I agree with that:) Nit picking on finer less
essential points that don't amount to a hill of beans?

I've been down the light bulb road long enough. I'm quite content with what
I know there and plant growth. I am not wavering in my opinions in this

Well I liked my Quartz 3000K lights when I had them. I like a softer yellow
color. So do many plants.

Well, it's alright to go there, just _make sure_ you come back:) You make
everything as controlled as possible then you start removing things to see
how and what works when it's gone or adjusted.
Remove the RO water
Remove the pH controller, solenoid, bubble counter, check valve.
Remove the PO4 remover.
Remove digital temp controller
Remove the heating cables
Remove all the junk till you have the basic three(lights, CO2 and

Pretty close now from what I can tell.
A little here and there and to take into account for different plant types
and fish loads but from what I've seen a common point can be reached.

Diana's book also can be a commonly reached non CO2 method. I use that too.
I just found that deep flourite does a nice job at that exact same thing
instead of soil. The substrate only gets better as time progresses. Colors
are better too. I'd like to do some side by side runs with both types.

CO2 introduces another realm. But It doesn't have to be such high
maintenance as some may contend. Lower lighting, slower growing plants(at
least a good % of tank space) and covering the basics can make for a lower
maintenance tank. Some folks want a hand's off. Most don't mind a little
