The World's Most Precise CO2 Regulator

The CarbonDoser® Electronic CO2 Regulator V2.0 is used for measuring Carbon Dioxide injection in freshwater planted aquariums, or with calcium reactors in saltwater applications. Unlike traditional regulators that use needle valves which are prone to pressure-related inconsistencies, this CarbonDoser regulator employs an electronic solenoid valve that opens and closes rapidly, ensuring precise and stable CO2 output. Once set, the bubble rate remains consistent within a margin of just +/- 1/1,000 of a second, effectively eliminating the issue of CO2 “dumping” seen in other regulators, giving you the most precise and consistent "bubble rate" on the market.

The new V2.0 allows for the aquarist to position the CO2 cylinder out of the way in a remote area, then mount the electronic box anywhere such as up on a board with all the other electronics and controllers.

Installation Instructions:

1. Attach and tighten to compressed tank.

2. Conduct a simple 'bleed down' test.

3. Please be sure the "perma-seal" (threaded brass piece with rubber O-ring) is installed either into the regulator or the cylinder. This is what creates the seal between the regulator and cylinder. You do not need Teflon tape on the threads here!

Ensure regulator black knob is closed (counter clockwise all the way out) NOTE: If the co2 cylinder is opened while the knob is engaged, the high pressure could damage the low pressure gauge, or affect its accuracy and void the warranty.
Open main valve on tank (very, very slowly)
Note pressure on gauge
Close valve
Wait 5 minutes
If successful, (no seepage) the previously noted pressure should NOT have bleed down reduced at all.
If the pressure dropped: remove the regulator from tank AND REPEAT process.

4. Start out slowly when adjusting co2 (too much Co2 will kill your fish)

5. To really get used to the Regulator, we suggest you take a glass of water, and simply put the Co2 tubing in the water to get a feel for the bubble count, and the size of the bubbles. This small test will really give you an idea of the broad adjustability of the unit.

6. To adjust the bubble count, turn the dial from 0-10. It is adjustable from 4.66 bubbles per second all the way down to 1 bubble per 10 seconds.

7. To adjust the size of the bubble simply adjust the knob. Clockwise raises the pressure and therefore increases the size of the bubbles and counter-clockwise lowers the pressure and therefore decreases the size of the bubbles.

8. As previously stated, we strongly urge you to take your time and experiment with the unit before actually applying it your CO2 reactor or calcium reactor. Quite quickly, you will begin to see its incredible range of adjustability and accuracy.
