I'm almost ready to throw my diy co2 together. I plan on doing one of the 2 liter bottle cheap ones. Will i need a valve or something incase the levels co2 levels get too high. And what is a safe level, and how do you test for it.
I was originally just going to use an air stone but somone said this would be good.Bearfan said:What kind of diverter do you plan on using?
