NICREW CO2 Aquarium Regulator
Precaution
- IMPORTANT! Before attaching the regulator to the CO2 tank, slowly open the tank valve wide open for 3-5 seconds to blow out any sediment that may be in the tank valve. Reclose the valve tightly. Whenever you are opening the tank valve, do it extremely slowly to avoid damaging the inner seals in the regulator.
- Make sure the washer is seated evenly in the regulator valve. Then attach regulator assembly to tank. DO NOT OPEN THE TANK VALVE YET.

Setting Up Your System
- Tighten the regulator on your CO2 bottle with a wrench.
- Unscrew the bubble counter and add four fifths of the water.
- Close the needle valve by turning it fully clockwise.
- Plug the solenoid into a mains socket.
- Open the gas flow from your CO2 bottle. The cylinder pressure gauge will show the cylinder pressure. Your pressure reducer now is ready for use.
- After the installation of the bubble counter and diffuser, turn the needle valve counterclockwise, then gas will flow from the regulator to the diffuser through the bubble counter. As soon as you see bubbles coming out of the diffuser, it indicates that the system is fully pressurized. You can adjust the desired bubble rate by adjusting the needle.
Note:
-
CO2 is heavier than air and will spread downward from the distribution points.
Make sure the distribution tubing is secured and does not interfere with your lighting or light movement systems. -
As a hint, 1 bubble per second is suitable for a 150 L aquarium. Adjust your dose accordingly, 2 bubbles per second for a 300 L aquarium.
-
Don’t forget to provide a CO2 tube long enough to place all equipment in the aquarium or other furniture. The longer the tube, the greater the loss and the longer it takes to find a leak.
-
We recommed to test the pH and kh before and after turning the lights on and off to determine the level of dissolved CO2. It should be kept between 20 to 25mg / L.
Check for Leaks
- It is recommend that each time you reconnect the regulator to the CO2 supply that you check for leaks. Identifying a leak from the outset is a much more desirable result than discovering there is a leak only when a substantial amount (or all) of your CO2 cylinder has leaked.
- The easiest way to check for leaks is to cover all of the joins with soap suds,and look for any sign of bubbling, and also listen for a ‘hissing’ sound. If your regulator has a solenoid, it is recommended that you switch off the electricity supply prior to applying soap suds. Please also try to only use the soap suds themselves, and as little water as possible.
Disconnect the CO2 Bottle
If you want to disconnect the regulator from the gas cylinder, it is important
to remove the gas contained in the regulator. Firstly, close the valve on the
gas bottle and then open the regulator needle valve to use residual gas. When
the regulator’s pressure gauge shows zero, you can safely disconnect it from
the cylinder.
