Hands down the CarbonDoser® is the most reliable and precise CO2 regulator on the market.
This product has forever changed the introduction of CO2 injection for freshwater planted aquariums, or a calcium reactor for reef aquariums.
The problem of "dumping" is completely eliminated with the CarbonDoser® 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 its 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 other regulator that relies on a needle valve to ever be consistent. The CarbonDoser® regulator does away with the 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. The low-pressure gauge goes up to 45 lbs but it can be measured up to 60 lbs.
