Great. My small CO2 needle valve won’t turn off, no matter how much I tighten it. Doesn’t really seem stripped or anything either...last night I had to actually, physically remove the diffuser from the tank since I couldn’t shut it off,,,

That's the thing! Needle valve is for fine flow control, not to be used for on/off. Constant closing and opening of the needle valve leads to damage to the needle.
