If you’re looking to have a flourishing planted tank, you have to ensure that they’re receiving the correct amount of CO2.
Insufficient, and they’ll end up dying. If you overdo it, you’re at risk of injuring your fish and promoting algae growth.
This is why investing in a high-quality CO2 regulator is among the best ways to ensure that you’re providing the highest levels of CO2 without putting your aquarium in danger.
However, there are many different regulators, and not all of them are created equal.
Aquatic plants in freshwater need the exact nutrients as terrestrial plants.
This includes iron, nitrogen, phosphorous as well and other elements.
Land plants extract carbon by absorbing CO2 (CO2) out of the atmosphere.
Aquarium plants also require carbon. The issue is that carbon dioxide is usually not present in aquariums.
It is normal that aquarium plant species starve for carbon since the tanks naturally are low in CO2. The carbon dioxide that is available is rapidly absorbed to the extent that plants can use it.
Insufficient carbon dioxide causes leaves to become yellow with slow growth and ultimately, death.
This is why CO2 fertilization is crucial.
Fortunately for you, I’ve conducted a great deal of research in order to locate the best CO2 regulators available at reasonable prices.
In this best aquarium CO2 regulator reviews and buyer’s guide, I’ll give you my suggestions for selecting the top CO2 regulators, and then, at the conclusion, I’ll go over some of them.
Overview of Best CO2 Regulator For Your Aquarium
Last update on 2024-07-27 / Affiliate links / Images from Amazon Product Advertising API
Better plant growth means fewer algae
The intense illumination utilized in aquariums with planted plants allows algae to overtake the tank.
However, when the aquatic plants are flourishing and algae are under control, they remain. This is because they remove nutrients and deprive algae of food.
But, if one of the vital nutrients is deficient, the growth of plants slows down. Because CO2 is insufficient and plants are unable to grow, they will become slowed down.
Liquids and tablet plant fertilizers provide minerals and trace elements, however, they do not add carbon dioxide.
The natural control of algae is a further reason to include CO2 in your planted aquarium.
How can you add carbon dioxide to your aquarium?
The most secure method is injecting carbon dioxide gas directly into the aquarium’s water.
There are plenty of CO2 gas sources within tiny paintball bottles or a 5 to 10-pound CO2 tank. Small paintball bottles are perfect for nano tanks that do not require a large amount of CO2.
Small canisters are simple to refill at sporting goods stores.
The aluminum or steel tanks are ideal for larger tanks that require high CO2 fertilization. The tanks can be filled by welding supply companies and beer distributors.
How do you inject the gas into the aquarium’s water? By using a CO2 regulator kit!
CO2 regulators for planted aquariums
For your plants to be fed carbon dioxide, you’ll need a CO2 regulator kit. The regulator screws on your CO2 tank.
It controls the pressure released from the tank. The indicator on the regulator measures the pressure inside the bottle.
The regulator lowers the pressure to allow you to add a tiny gas stream into the aquarium. This gas flow into your aquarium can be controlled using an adjustable valve for fine adjustments.
The CO2 is released through the valve’s silicone tubing, and then into a diffuser that is attached to the aquarium. The diffuser and tubing are usually not included in the regulator.
You’ll require a regulator specifically that is specifically designed for use in aquariums. CO2 regulators for industrial use lack the fine-adjustment valve needed to regulate the small amount of gas that is used in a plant-based aquarium.
The hose will be connected between the regulator and the diffuser. The CO2 has to be able to diffuse into the water, so it is absorbed by plants. The diffuser creates small bubbles which help the CO2 dissolve in the water.
Some regulators include bubble counters that let you know the amount of gas flowing into the aquarium. Most regulators feature an electronic solenoid valve that allows for an automatic shut-off of gas during the night.
Aquarium CO2 regulators’ components:
- Connector threaded for paintballs or big gas tanks
- Gauges for gas and tank flow pressures
- Fine-adjustment valve
- Bubble counter
- Electronic solenoid valve

Why You Need a CO2 Regulator
If you’re trying to maintain well-maintained tank plants it’s likely that you’ll require CO2 injection, since it plays an important part in the way that plants process photosynthesize.
I’m not going into great information about photosynthesis, because I’m guessing you already know the basics of how it works.
Here’s what you must be aware of:
Wild plants take in CO2 in large amounts from substates of nature (mud and so on. ) and also degrading plants.
In your enclosed aquarium, CO2 is not as abundant the tap water is drained by CO2, and decay in plants is very low.
You should therefore add CO2 by injecting it. However, you must control it.
In addition to wasting dollars (you’ll pump more gas than you require) excessive CO2 could cause excessive algae growth because your plants won’t have the capacity to utilize the CO2 quickly enough to compete with algae.
You could also cause death to your fish as the high CO2 levels that are high can saturate the oxygen and choke your fish.
Each aquarium is unique. What amount of CO2 required will be contingent on certain aspects:
- The amount of your tank
- Plant type and the number you have
- How much light do you provide your plants
- The amount of fish that is in your tank
- The amount of water movement
Determining how much CO2 your tank requires may require some adjustment. The fastest and most efficient method for this is to utilize drop checkers.
Drop checkers are simple devices made from either plastic or glass.
It’s in your tank. With a solution, CO2 leaks out of your tank into the drop-checker and triggers a reaction that causes that solution’s colors to alter.
- Not enough CO2 = blue.
- The levels of CO2 in green are right on
- Too much CO2 = yellow
Why You Don’t Need a CO2 Regulator
High-lit plants are more likely to need CO2 due to greater levels of light the more quickly plants are able to expand, the more CO2 they need.
But, if you keep plants with low lighting are less stimulated to develop.
The extra injection of CO2 isn’t necessarily required since there is usually sufficient CO2 derived from the surface of agitation, fish respiration, and the organic decay in dead plant matter.
It doesn’t mean you cannot utilize CO2 injection. In fact, adding it to your plant can increase the growth and health of your plants. You’re only going to require smaller amounts of CO2.
How to Choose the Best CO2 Regulator for Planted Tanks?
CO2 regulators used in the industrial sector are large and expensive and ineffective at dialing in the precise gas flow needed to maintain aquariums that are planted.
The aquarium’s specialties are cost-effective and specifically designed for CO2 fertilization.
Certain regulators are specifically designed specifically for gas tanks that are large and have CGA-320 threads. Some are made specifically for paintball bottles.
You can utilize the screw-on adaptor to allow for the usage of two kinds of containers for gas.
Choose a regulator with a special (non-industrial) small adjustment valve. This will make it simpler to adjust the flow rate of gas.
When deciding on a regulator, make note of the aspects we’ve covered and check how the regulator aligns with what you require.
I’m now going explain to you what I believe to most important aspects to consider when you are looking to purchase CO2 regulators and the things I’ll review based on.
This includes:
- Ease of use
- Readability
- Are you sure it’s a dual-stage?
- What CO2 cylinders it is compatible with?
- What is it composed of?
- What kit comes with? (most important)
Let’s break them into pieces one at a time.
Ease of Use
In the majority of cases, the process of the installation of your CO2 regulator is quite simple. It’s usually just as easy as connecting a couple of tubes, and then turning a couple of knobs.
But, you don’t do not want to be able to spend hours turning and adjusting the knobs until you get the proper quantity of CO2.
The good news is that even the best CO2 regulators will need some delicate fingers. However, you shouldn’t allow it to be too much.
Readability
What I’m referring to is how simple for you to understand gauges. If you’re like me, and your eyesight isn’t as good as it was in the past it’s important to have a simple-to-read gauge.
Is it Dual Stage?
If you’re just beginning to learn about the hobby, it’s important to learn about these. Dual-stage regulators include two different regulators that are integrated into one.
The initial stage lowers the pressure to a controlled (constant) PSI for the second stage.
This stops fluctuations caused by changes in PSI in the tank. Two stages can provide additional security.
The true, single-stage regulator is less costly and is generally used without issue.
However, it can be risky, and is harder to obtain an accurate and reliable output.
What CO2 Cylinders is it Compatible With?
This is contingent on your specific situation. If you plan to utilize your regulator for several tanks, you’re likely to require one that’s compatible with the larger 5lb CO2 tanks.
Also, you’ll replace your CO2 every now and then.
On the other hand, If you’re finding it difficult to locate 5lb CO2 cylinders, or you only require it for a single tank (depending on the size).
It is possible to consider purchasing one that works with the standard 24oz paintball cartridges. They, in fact, are very simple to locate.
What is It Made of?
The higher quality of materials means it’s likely to last longer. Everyone doesn’t want to purchase something that is going to crack easily. Brass and stainless steel are the most reliable options.
What Kit Does It Come With?
Certain of them tend to be more of a benefit while others are essential. I’ll tell you what we’ll be discussing about one another.
Needle Valve
If you are looking for a secure high-quality regulator, a quality needle valve (sometimes known as a pressure relief valve) is essential.
It allows you to have exact control over the quantity of CO2 that enters your aquarium.
Needle valves permit you to precisely adjust and regulate the speed of the flow (CO2 bubbles/second) to your preferred amount.
It’s essential to purchase an excellent needle valve as it can help to avoid the terrifying “end of tank dumps”.
When the CO2 level in your cylinder decreases it will decrease the pressure and can cause an increase in pressure, and possibly dump any remaining into your aquarium.
A good needle value will stop this.
Serving as a gateway, managing the amount of CO2 that enters your aquarium, regulating the rise in pressure of output as well as preventing the “dump”.
Bubble Counter
It is a visual tool that allows you to gauge the number of bubbles that are entering your aquarium.
The bubble counter itself isn’t an issue since many do not include one. However, I strongly suggest that you purchase one since it allows for small changes to your flow.
Solenoid Valve
A must I believe.
Solenoids save cash by preventing your CO2 from being wasted during “lights-off” hours when your plants don’t require CO2 as they allow you to turn it on an automated timer. It’s even better with a lamp that can tell you when it’s turned in operation or not.
You can now shut off the CO2 supply by hand on the CO2 regulator that doesn’t have one. In most homes, there’s not always anyone around at the appropriate moment to turn off the CO2 supply. This is among my favorite gadgets including regulators.
Gauges
It will come with two gauges, one for high pressure, and another to measure low pressure.
The high-pressure gauge should have a reading of at minimum 1000 psi because the majority of CO2 tanks have 800 psi.
Low-pressure gauges should show between 15 and 30 psi and the maximum is 200 psi. 30 psi gauges usually indicate that the regulator is operating at up to 15 psi.
If it is lower, it will produce 10 or less psi This is not suitable for aquariums.
Pressure gauges with a low pressure of more than 200 psi indicate that it is difficult to regulate the pressure to the ideal range of 15-30 psi.
Dual-gauge does not mean dual-stage.
Check-Valve
If it’s not in the kit, then you’ll have to purchase one.
This is a crucial safety measure, as it prevents an unintentional backflow of water from the tank into the CO2 regulator.
If your CO2 dissolves in water, it returns to the tubing after the CO2 injection has ended.
If you do not possess a valve for checking installed, the water can get into the regulator and cause it to break.
Tubing
It’s not a problem if the kit has this, but it’s an added benefit since it is impossible to have too many. It’s cheap and it’s easy to buy this on its own.
Be sure to select CO2-resistant tubing. The regular airline tubing doesn’t possess the right characteristics to be safe for use.
The Washers
It may seem like a small amount. However, if your washers have a size that is unusual and shape, it could be difficult to locate replacements.
If I don’t mention washers in my review, it’s because they’re standard and readily available.
FAQs
What is the best CO2 regulator for a fish tank?
The most efficient CO2 regulator with a single stage comes from it’s the INKBIRDPLUS Aquarium CO2 Regulator. Its neat design and precise trimmer valve that allows for fine adjustment give it an advantage over the competition. It also comes with a bubble counter as well as a check valve, which is everything you require to have an effective regulator.
What is the easiest CO2 for aquariums?
Aerosol CO2 sets may be the cheapest and most efficient method to include CO2 in an aquarium that is planted. They are comprised of a CO2 bottle that has been pressurized as well as a hose as well as a diffuser. Click to open the CO2 can and the diffuser is filled the diffuser with Carbon dioxide gas.
Can too much CO2 hurt fish?
A high level of carbon dioxide is harmful as carbon dioxide diminishes the capacity of fish’s blood vessels to carry oxygen. Fish that drink water with high levels of carbon dioxide (>10 12 mg/L in some species of fish) could be in danger of dying even if oxygen levels are elevated.
Are cheap CO2 meters accurate?
The cheapest devices that include multiple sensors that measure the volatile Organic Compounds and Formaldehyde alongside CO2 aren’t recommended.
Final Recommendations
When CO2 regulators are concerned it is common to receive what you spend for. The most reliable and effective regulators will be more expensive.
CO2 can be deadly If you put it excessively in your water. Therefore, it’s better to choose reliability over the economy in this case.
Although each regulator provides the option of using CO2, some are different from the rest.
Fzone Triple Stage featuring DC solenoid and bubble Counter includes all the features you need to feed your aquarium.
The regulator is equipped with an adapter that allows it to be utilized with paintball or standard gas bottles. The valve for fine adjustment is designed to regulate gas flow to smaller amounts without much adjusting.
If you are planning to use the large CO2 gas bottle but do not require a solenoid valve then consider using the Tunze Dual Gauge CO2 Regulator.
It comes with a specially designed fine adjustment valve, as well as robust lab-quality construction. You can also add an individual bubble counter, as well as other equipment to make it a customized design.
If you’re looking for the overall performance and quality in terms of overall quality and function, in terms of overall quality and function, the MagTool Dual Stage regulator is my top option. Dual-stage functions protect against unintentional CO2 leaks when the gas level drops within the regulator.
In these best aquarium CO2 regulator reviews, the second option I would suggest is the INKBIRDPLUS. It’s not dual-stage however, it’s easy to read and comes with a trimmer valve, designed specifically for use in aquariums, which allows for fine-tuning.
Happy fishkeeping!
