Default DIY CO2 Question

Thanks, Steve, that's what I'm going to do for the big display tank in the
living room. My biggest worry was using an airstone and having it get
gooped-up with back-pressure resulting. I've got a 20-long in the kitchen
(small and easy to putz around with) that I put a bottle on yesterday with
an uncapped line inserted at the bottom of the riser. The impeller seems to
do a decent job of breaking up the bubbles and then blasting them back down
to the bottom of the tank. At any rate, by midafternoon my sagittaria
subulata subulata jungle and riccia rock were bubbling like crazy!

With my experience with DIY CO2, it's kinda hard to say how much gas is
being produce or being injected to the tank.

I'd say put it into the venturi. Much easier to remedy in case of

problems.

I'm about to start a batch of yeast in a soda bottle which I'm going to

use
to inject CO2 into my power head. Does anyone have an opinion on

whether
it's better to feed the bubbles into the venturi or into the riser tube

(no
prefilter)? I can't inject it into my canister because the gas makes it
rattle.

Also, I'm collecting horror stories about exploding DIY yeast systems to
tell my wife while I'm hooking it up (in the living room).

Oh, and I may be looking for a roommate...

Thanks,
kush
