Hello Friends, I have my new super cool CO2 tank all set up and have two questions. 1. I have a 5lb tank of CO2 going through a regulator and then out to a vortex reactor in the tank. The tank is 29 gallons. The regulator is set to 10.5 PSI and I am getting a bubble about every 4 seconds. Does any of that rings bells for you? 2. Is there a way to add too much CO2? How do I know? Thanks Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
