Why Do I Need A CO2 Reactor In My Fish Tank?
Buying an aquarium and keeping fishes inside it is something anyone can do. But, keeping them healthy and maintained is another story.
There is a lot more that your fish need besides water and a few decorative pieces. There is more of a fish tank than a bubbling filter and every fish enthusiast is aware of this. Maintaining the perfect fish tank requires a balanced amount of oxygen and carbon dioxide as well.
All types of fishes and aquatic plants need Carbon Dioxide as it is a need for them to thrive and live healthily within the tanks. However, it can be a little difficult to get the right level or the perfect balance of oxygen supply with carbon dioxide.
This is where a CO2 reactor comes in handy! Let us see why they are so important and necessary for good fish and plant health.
What Is A CO2 Reactor And How Does It Impact My Fish?
CO2 reactors are devices that help keep a balance between oxygen and carbon dioxide content in a fish tank, as the surplus of any one component can cause more harm than good. These optimum levels are not only necessary for plant growth but they also keep the fishes healthier and happier.
A fish tank’s only source of CO2 is from the outside air. This makes the amount of naturally occurring CO2 very less as the fish tanks are usually covered by a lid that mostly stops any flow of carbon dioxide from the atmosphere into the tank.
CO2 reactors offer to provide fish tanks with the required levels of carbon dioxide gas. What is even better is that CO2 reactors are completely risk-free. They are extremely safe to use in your tank. They have no effects and are easy to install and make use of.
More importantly, depending on the reactor you use, most reactors have automatic valves. These valves can control the release of carbon dioxide into the water. So, the only impacts that you see are happy fishes! (And a happy you, of course!).
How Does A CO2 Reactor Work?
The main purpose of a reactor is to inject CO2 into the fish tank. A reactor releases CO2 in the water in the form of bubbles, which should ideally dissolve in the water current to distribute the necessary nutrients to the plants and fishes in your tank.
CO2 reactors are the most preferred method of CO2 supply, recommended by many pro users.
Now this brings me to a comparative analysis of which are the best reactors available in the market.

Best CO2 Reactor Buying Guide
Here, I have put together some necessary things you might want to consider before buying a reactor. Read on and understand how to find the perfect product.
Fish Tank Size
How large is your fish tank? It’s important to keep in mind that not all reactors are able to work for all sizes. Reactors are supposed to diffuse 100% of the CO2 and if the size is bigger than its capacity, the quality is compromised.
So measure your fish tank capacity and then check the reactor’s packaging to match the capacity it is suitable for.
Ease of Installation
Fishes are very sensitive creatures and it is important to note that moving them too often can cause traumatic experiences for them that negatively affects their wellbeing. While considering a reactor, think about how easy it will be to install and how much of a disturbance it will cause for your fish.
The fact of the matter is, not everyone has the kind of money to spend on their hobbies – we have so many other things happening in our lives that we can’t always pay top-dollar for things. That being said, it is important that when you’re looking for a CO2 Reactor, you pay a reasonable price for it.
A good CO2 Reactor – as we’ve seen with some of the examples given – does not need to drain your wallet; so make sure to compare prices before making your selection.
One of the few problems that CO2 Reactors can cause you is leakages. This can be due to a variety of reasons, one of which is incorrect installation or because the pipes are too big or too small. To rectify this, some reactors have attached ‘leakage proof’ o-rings that adjust for size differences and prevent leaks.
So when shopping around, check to see if the CO2 Reactor you fancy comes with a ‘leakage proof’ system in place or if you need to buy the necessary equipment to stop the leaks yourself.
Necessary Components To Set Up A Reactor?
An ideal CO2 kit comes with the reactor, top quality tubing, suction cups, valve and a pressure gauge. Moreover, the tank owners; particularly, love to find ceramic replacement dishes in the kits, the perfect solution to their tank cleaning concerns.
Make sure to check the parts available with the reactor, as you would be required to fit some extra pipes or hoses to secure your tank glass against the reactor and protect the floor from any leakage.
CO2 Reactor Vs. Diffuser – What Is Best For My Fish Tank?
Although both are CO2 regulators, may beginners get confused between a reactor and a diffuser. Let me explain some major differences for you understand.
- These are CO2 regulators that offer supply of CO2 to the tanks by breaking down the bubbles into tiny bubbles.
- These are good for small and medium sized tanks.
- Diffusers are good distributors of CO2 in the tanks, but they are mostly not 100% efficient.
- These require to be soaked to clean, which is a difficult task for most users.
- It also creates a mist-like diffusion. Some people tend to dislike this misty look.
- These are CO2 regulators which provide 100% CO2 dissolution.
- Unlike the diffusors, they do not release CO2 in the tank directly; but they mix it with tank water within the reactor before they release it.
- They do not create a misty spray of bubbles, keeping the aquarium clear.
- Due to their availability in different sizes, they are good for tanks of various sizes.
- These are very easy to clean as they can be taken apart conveniently.
What Is The Best Way To Maintain My CO2 Reactor?
The right installation is the most important factor in the performance. Make sure you follow step by step instructions given on the package. Always try to dip the hose and tubes in warm water before you try to slide them on to avoid breakage.
It is also best to place the reactor closer to the bottom of the tank for best results. Water and chlorine bleach together can work wonders for a reactor’s maintenance. Simply soak the reactor into the solution and then rinse and wash under clean.
Frequently Asked Questions
