Jeremy:
I am using two 2-liter Gatorade bottles (actually they are about 1.8
liters) for a 20-gallon tank and just bubbling the CO2 through an
airstone. I'm afraid that if I use a reactor with my two-bottle system
in such a small tank I might end up dissolving too much CO2,
especially when the yeast are fresh. If you really are seriously
considering setting up such a large planted tank, then why bother
with the DIY CO2? I know that a compressed CO2 system runs into
money, but I think you'll need at least three or four 2-bottle units if
you go with yeast-sugar. If you do it, I would hook them up as
independent 2-bottle units to minimize downtime when changing the
yeast-sugar solution, and change the solution in each bottle within
each unit every two weeks on a staggered schedule. This seems to
me like it will be an awful lot of trouble.
Adeana asked about slime building up on her DIY CO2 line. Yes, I
think we all observe this from time to time. I just wipe it off when it
appears and make sure that the line is not clogged. It helps to have
a bubble counter made from a small water bottle between your yeast
generator and the outlet of your system.
Hope this helps,

over.
