John,
I attempted the same approach to see how it would work. I
couldn't
get the concentration of CO2 high enough, but I might not have let it
sit long enough. What concerned me was that the top of the trickle filter
has some openings and I didn't think that I could keep a high enough
concentration of CO2 in the chamber. Given the oxygen level in the water
because of the plants I suspect that lack of oxygen is not a problem for
the aerobic bacteria.
Question for the chemist types: Is the fact that the trickle filter
chamber has openings on top a problem with this method? I don't want to
waste the CO2, but it would be nice to free up the secondary magnum 350
I am using as a CO2 reactor for other tanks.
Ted.
