I set my diy co2 system last night, i was done by 12, its about 11:40 am now and im still not seeing any bubbles, how long does yeast take to ferment? Did i just do it wrong? Oh big one(?), i made a pvc diffuser, the pvc glue(blue gunk) and the primer wont emit chemicals and kill my fish will they? Im really worried about that.
