Re:diy co2, Anyone ever setup a diffuser like this one? The description is good, but there's small details I'm confused about. Like how it's kept in place? Where do the bubbles escape the tube? Do they, or does it dissolve before bubbling out? Would it be just as effective to pipe the co2 hose into the intake pipe of my canister, without drying out the pump? I should probably open a new post, but thought I'd ask here first...
