[APD] Re: DIY CO2 Disaster

Does this method also act as a check valve?  What I'm concerned is  if the aquarium water gets siphoned back and fills the  "tiny bottle"  and then water gets pushed back into the co2 generator bottle and then the yeast and alcohol spread out and eventually get into the aquarium or does this not happen?

And if you extend the inlet tubing to the bottom of the overflow bottle 
and put a bit of water in it, it will also serve as a bubble counter.
