.....I was thinking if I could create a air-sealed sump where I put
all dead leaves and other organic matter from my trimmings.
In this air/gas-tight sump I drill two holes: One for a air-pump
with air-stone to make a real good aerobic climate for the
decompose-process. In the other hole I put tubing to lead
the sump-produced gases (CO2 amongst other things)
into my low-tech aquarium.
Would this work? Would it stink like h.ll? Would the
produced CO2 be sufficient to make a difference?
Yes! it should work, or at least it is certainly worth the effort of
finding out. I have been thinking of doing something like this for
years. I have always thought, "why produce CO2 anaerobically, when
you can get so much more of it from a given amount of organic matter
aerobically?" Obviously you will have to fiddle with the air flow
rate through the system to get the most out of the CO2 produced. You
may find that it is best to let CO2 build up in the system overnight
and only run air through the system at certain times during the day.
Leaves may decompose a little too slowly. Try mixing some uncooked
oatmeal with the soil. It won't stink unless the whole system goes
completely anaerobic. Decomposition by various fungi in the presence
of oxygen is pretty much odorless. The only way to find out if it is
going to make enough CO2 to make a difference is to make
measurements---pH and KH and use the tables, or use a CO2 kit.
Actually, you can get a pretty good idea just by checking the pH and
see how much it drops when you start running the air from your
compost pile through.
