I just DIY a CO2 reactor for my 1ft tank... at first I thought it is not working cos waited for so long no bubble... then I found out that the air valve (metal type) is leaking so I connect the ceramic stone directly to bubble counter and to the reactor. Gosh! Now the bubble keep increasing.... how do I regulate it? It's like having 4-5bps and my col telling me they smells bread smell....

Can i leave it over night? I'm afraid when the aircon turns off at night, then the next day my whole office will stinks yeast smells.
