Thank you for replying. Even though I have kept plants in my tanks for well over a decade, I have never used pressurized CO2. I have read a ton, but that doesn't mean I understand it all... that will just come with hands on experience lol.
So, if I bought a good needle valve, solenoid, and bubble counter... I could just use that on the dual stage regulator that I buy in a couple months? Without knowing what regulator I'm going to buy, is there any way to know if there will be compatibility issues or are they pretty much universal?
I planned on buying a diffuser (I do have the diffuser that came with the ISTA CO2 package) and a drop checker.
