CarbonDoser® Electronic CO2 Regulator V2.0 (complete system: with remote box option)

Now built with the TUNZE® (German Built) Regulator (Exclusive Edition with PSI rather than metric Bar gauges)

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 electronics/pH controllers/ETC.

The 1/8″ tubing from the Reg to the Box is very pliable and easy to use similar to a wire!John Guest push-in fittings.

  • CarbonDoser® exclusive check valve
  • Polyurethane tubing (1/8″ from Regulator to CarbonDoser® V2.0 Electronic Box & 1/4″ from Box to check valve to Reactor or diffusor.
The CarbonDoser® Electronic CO2 Regulator V2.0 has forever changed the introduction of CO2 into an aquarium. Used for CO2 injection for a freshwater planted aquarium, or a Calcium reactor in a saltwater application. We guarantee that nowhere on this planet can you find a BETTER or MORE PRECISE regulator! The problem of “dumping” is completely eliminated with this regulator. Dumping is always a problem with ALL OTHER regulators which utilize a needle valve. Simply because, a needle valve relies on the pressure on both sides of it for accuracy. So, even though you have it set at a certain “bubble rate”, once the pressure in the cylinder (or the outside atmospheric pressure) changes, so will the amount of CO2 that passes through the needle valve. This is why it is physically impossible for any and ALL other regulators that rely on a needle valve to ever be consistent. This regulator does not have a needle valve, but instead, it has an electronic valve that opens and closes in a fraction of a second, (each “opening and closing” equates to a bubble) and, due to the fact that it is “electronic” the “bubble rate” can NEVER change. Once it is set, it can never vary more than +/- 1/1,000=of a second.

  • Pinpoint
  • And many any others
  • Just the electronic box option:  This is for the user that has invested a ton of money in a high $ fancy shiny regulator, only to discover that they are never consistent. Rid yourself of the problematic bubble counter, solenoid & needle valve and use this remotely.
  • “Multiple remote electronic box option: This allows for multiple electronic boxes for several aquariums but only 1 CO2 cylinder and 1 Regulator.  (Please contact us for specifics/options.
