8 Tips and “Must Knows” for your CO2 Regulator and Cylinder!

  1. Don’t just remove your CO2 regulator when it’s time to refill. Before you remove it from the cylinder, make sure that you relieve the working pressure from the low pressure gauge. This prevents future damage to the low pressure gauge when you re-install the regulator onto the cylinder.
  2. Vent your CO2 cylinder for 1 to 2 seconds after you fill or refill it, before installing any components to the cylinder. This removes any debris that may be lodged in the cylinder valve. Preventing debris from entering the solenoid of your CO2 regulator and prolonging the life of your CO2 equipment.
  3. After you fill or refill your CO2 cylinder, make sure the cylinder reaches ambient room temperature before re-installing your CO2 regulator. This ensures that the pressure in the cylinder has equalized so that your regulator can take accurate pressure readings.
  4. Don’t forget to put your seal between the cylinder valve and regulator. When using a permaseal, hand-tighten only, a wrench is usually not required and may damage the permaseal if used.
  5. When you are ready to install your regulator to the cylinder make the connection as tight as possible. Use a crescent wrench or CO2 wrench to ensure maximum tightness, so there are no leaks or loss of CO2.
  6. Never over-tighten the bubble counter on your CO2 regulator. Doing so may damage the components that protect your regulator from contamination, or cause the bubble counter to break off.
  7. Don’t forget to use a check valve. To protect your CO2 equipment, install a check valve in your CO2 tubing, close the the aquarium but not in it. This prevents water from creeping out of the aquarium through your tubing, and towards your regulator.
  8. Last of all, if you ever have any questions or problems with your CO2 regulator ALWAYS contact us. Never attempt to diagnose or repair your regulator without prior consultation.
