Setting up a CO2 injection system:

  • Screw on and fasten the pressure reducer onto the CO2 bottle.
  • Attach a CO2 hose to the pressure reducer
  • Connect the other end of the CO2 hose to the solenoid valve. Mind the arrow on the valve indicating the CO2 flow direction.
  • Attach a CO2 hose to the output of the solenoid valve.
  • Connect the check-valve to the hose. Mind the CO2 flow direction arrow printed on the check-valve.
  • Attach a 3-5 cm long CO2 hose to the output of the check-valve.
  • Attach the bubble counter to the end of the hose. It should be vertical, with the small narrowing (this is where the CO2 drops will appear) on the bottom side.
  • Carefully fill the bubble counter with water or the special bubble counter solution (recommended to have).
  • Attach a CO2 hose on the upper end of the bubble counter, take the hose into the aquarium in case of diffusers or outside in case of reactors.
  • Connect the diffuser (inside the aquarium) or the reactor (outside the aquarium) to the end of the hose.

IMPORTANT: The set does not contain the CO2 canister by default. You need to check it to add that to your order. A pressurized CO2 bottle is required. Unfortunatelly CO2 cylinders not allowed to ship by the law. This is only available with in-store pick up.

CO2 diffusers will need to be cleaned every second week by bleaching them in a special solution - to keep them clean, elegant and operationally effective.
