Semi-Automatic CO2 System/bubble rate
I have a semi-automatic CO2 system using a pressure bottle, regulator &
decent valve etc.,
My needle valve is of good quality & sturdy (make unknown) but it is
incredibly sensitive. I only have to move the valve eg.2-3 degrees to make
quite a large difference in my PH.
Ideally, I want the valve to be less sensitive so that a quarter-turn would
only alter the PH by say 0.3 ? How do I do this ?
I was thinking of turning the output pressure down a little - is this a good
idea ? Or, is there a better way ?
