My CO2 bubbling for my calcium reactor is really weird. When i tune it, the bubbling can be very high now, and then it slows down later, and then the next day, it stops bubbling! The water even goes up the tube (dont worry, i have a check valve)....
Is there a problem with the control valve? or the main CO2 tank itself? The control valve is a normal one, should i get a solenoid one instead? or anyone can recommend a good needle valve?
