Question about setting up Co2 regulator
I am finally setting up a pressurized CO2 system after staring at a new empty intimidating CO2 tank for 5 years. I bought a nice regulator from Green Leaf Aquariums and it seems I misread the instructions on setting the low pressure gauge. It said to turn it to 10 and I did but afterward I realized it was not the 10 at the end of the dial, it was 10 psi on the inside dial - a much lower setting. Now I have no idea how to bring it back down. I have tried loosening the handle, shutting everything off and starting over - it is still dialed up all the way. Any advise for this dumb blonde?
