- CarbonDoser Electronic CO2 Regulator with John Guest Fitting - Aquarium Plant Life
Why Does BRS Recommend This?
This is the most reliable CO2 regulator on the market that we could find. Instead of traditional needle valves controlling the flow rate, the CarbonDoser® uses an electric solenoid that will open and close within a fraction of a second producing a single bubble. Since there is no needle valve, the CarbonDoser's® bubble rate will never change. You now have super precise control with unmatched reliability.
Electronic solenoid controls the bubble rate making it virtually impossible for it to ever change.

A good reliable CO2 Regulator and Solenoid is a vital part of any calcium reactor. Many traditional needle valve solenoids can change how much flow is let through over time with the ever changing pressure in the bottle. Aquarium Plant Life solved that issue with the CarbonDoser's® Electric solenoid design. Once you set the CarbonDoser® it will not change. The electric solenoid will open and close within a fraction of a second producing a single bubble.
The flashing LED will blink every time a bubble is produced

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.
Okay Option By Jim on 7/20/2019Jim would recommend this product to a friendThe CarbonDoser is a good option when it comes to co2 regulators - I ran one for at least six years. But the very best option is to consider a "dual stage" regulator with a quality needle valve meter. They can be very expensive, but can be custom belt and occasional found used for same or less than the CarbonDoser. The advantage is that you have much finer and reliable control with a good dual stage regulator setup on a control like the Apex. The main benefit is that will use less co2 which will help to reduce algae in the aquarium - after all reef tanks are not freshwater planted tanks that require co2 injection. You need just enough co2 to melt the calcium media.
great support By Homer on 3/5/2019Homer would recommend this product to a friendThought i had a problem with my carbon doser regulator, not letting out enough bubbles per second. Contacted BRS staff and they immediately sent out a email to the manufacturer. A couple hours later i received an email from the manufacturer telling me to call them up and they'll walk me through the problem. I explained to them, i initially set the knob to 1 bubble per second and wanted to increase it to 7 bubbles per seconds .. but it was still releasing 1 bubble per second. Representative explained to me .. it's "seconds per bubble " not bubbles per second. ( so that explains why it wasn't working ) for me to increase the bubble rate i would have to turn the knob counter clockwise.
BRS and Carbon Doser team are amazing.
Don't hesitate to buy this product , little pricey but worth every penny
Seems to work great so far By Jim on 10/24/2018Jim would recommend this product to a friendI bought one of these as open box from BRS. Turns out the low pressure gauge was damaged. I contacted AquariumPlants.com and talked to the somewhat rude man as described in an earlier post. He suggested I check to see if the gauge or regulator was at fault. Turns out it was the gauge, so they are sending a free replacement. So I'm 50-50 on their customer service ;) The unit seems well made, time will tell. I've used a needle valve on my previous regulator & it was finicky. This seems much easier to select the CO2 flow rate.
Awesome CO2 Control! By Houstonpam on 9/12/2018Houstonpam would recommend this product to a friendI have had a problem with cheaper regulators giving out and flooding my planted tanks with CO2 leaving my tank with lovely plants, but full of dead fish. When I noticed the CO2 running too quickly, I used the ultra fine tuning knob rather than the one on the CO2 tank and it slowed the CO2 back to a safe rate. I am in love w3ith the Carbon doser regulator!
Great Customer Service By Stephen on 6/7/2018Stephen would recommend this product to a friendI'm not one to usually write a review. That being said the customer service I just received from Mark was fantastic. I live on the west coast and to get a phone call from him at 5pm was a shock. He worked with me over several calls in a hour to resolve the issue I was having and got my reactor back up and running.
CarbonDoser w/ John Guest Fitting Sets A Standard By Lou on 6/6/2018Lou would recommend this product to a friendThe ability to accurately control your CO2 delivery in a calcium reactor is crucial in stabilizing the Calcium and Alkalinity of your reef system. This regulator is simply the best instrument available to that end.
Fairly Solid. RUDE COMPANY. By Wade on 2/13/2018Wade wouldn't recommend this product to a friendWhile my CarbonDoser does seem to function pretty well, It is touchy in that if it gets bumped it will sometimes not dispense CO2 and requires a quick jostle to get it to function again. On that note, considering the price one pays for these, the customer service is horrific. If one goes to the marked "carbondoser.com" it actually takes you to aquariumplants.com. I have had the misfortune of needing to call the number for aquariumplants.com on a few occasions for help or advice on the unit and everytime the same rude, condescending man answers the phone and speaks to you as though you are wasting his time and should not be calling him. I've never been able to get this mans name as he speaks way too fast each time he answers but I recognize his voice and attitude and he is always the one that answers. I'm not sure if this guy runs this whole company by himself or what but he has no business being the contact person for the company. So much to the point that I'm not sure the Carbon Doser is worth the price.
Aquarium Products Doesn't Support Warranty By David on 11/23/2017David wouldn't recommend this product to a friendI purchased 2 different carbon doser regs and both failed within 1 year. I shipped my latest one back to aquarium products for repair DURING the warranty period and they claimed it had saltwater corrosion inside DESPITE me using their expensive checkvalve. The sent me a bill for $90 for the repair which i refused to pay and they never sent me back my regulator. They basically stole it from me. I have read reviews online and this has happened to many others. This company is a fraud and the product is a rip off. You will be just as happy with an inexpensive regulator that you can buy online for $60-$100. Don't waste your money.
Worry free after 4 years By Corey on 10/21/2017Corey would recommend this product to a friendI inherited one of these from a friend in the hobby who passed away. He used it on a planted freshwater tank, I of course used it with my Apex for my CA reactor. For a regulator, this one is pretty pricey, but if you are looking for incredibly accurate and reliable C02 delivery this one is for you. I would have never spent this much on it myself to be honest, but now that I have had it for going on 5 years and it's never given me any kind of issues I can say that I'd buy another one.
Solid Product By Dan on 8/6/2017Dan would recommend this product to a friendVery solid build and accurate. I have only been running for a short time however running a calcium reactor has been a fantastic upgrade to dosing and this regulator makes dialing everything in much easier and more reliable.
wow By fishguy32903 on 8/16/2016fishguy32903 wouldn't recommend this product to a friendbeen using co2 regs since 1985 best yet
Worth every penny... By Rich on 6/23/2016Rich would recommend this product to a friendI'v ran this unit for the last 2 years, it is one of the best investments for your calcium reactor... Accurate and consistent EVERY TIME!... Easy to control via Apex / pH controller...
Do I need to order a solenoid for use in a Calcium Reactor setup to control on/off of CO2 coming through?
Just received doser has a gray colored check valve box instructions says to take apart and clean the valve looks solid and no direction on how to clean
The check valve should be lightly cleaned with warm soapy water to remove any contaminants or foreign materials from the manufacturing process.
