CO2 is necessary for aquatic plants. However, it’s a challenge to supply plants with an adequate quantity of CO2. An aquarium CO2 diffuser or atomizer solves this problem. How does a CO2 diffuser solve this? What are the differences between a CO2 diffuser and a CO2 atomizer, and a hygger CO2 diffuser review is a worthwhile topic of this article. The hygger CO2 diffuser is not suitable for every planted tank; it has certain limitations. Scroll down to find them with many other details.

What Is a CO2 Diffuser?
A CO2 diffuser is a device that makes the CO2 water-soluble so that the plants can use it. CO2 is necessary for plants, similar to O2 for humans. Plants use CO2 in photosynthesis. The same goes for aquatic plants, but they can use it when it is water-soluble.
CO2 diffusers have ceramic membranes. This ceramic membrane breaks down the CO2 into fine bubbles that are water-soluble. That water-soluble CO2 is readily available for plants in tanks. With a proper CO2 dosage, you can observe optimal plant growth in your tank.
What Can A CO2 Diffuser Do In Aquariums?
A CO2 diffuser serves various purposes in an aquarium. Here are some of them.
Improve the CO2 Level for Plants
Plants require CO2 during photosynthesis. Usually, in aquatic environments, the CO2 level is less than the optimal value. A CO2 diffuser improves the CO2 level in the tank and ensures the optimal dosage for the plants.
Optimize Plant Growth besides health
With an adequate CO2 level in the tank, plants show fast growth, strong root development, and lush coloration. A CO2 diffuser helps to achieve these objectives by providing adequate CO2 quantity to the plants.
Increase Oxygen Production
If things go optimally in photosynthesis, this procedure produces enough oxygen in the tank. This results in better fish and other aquatic pets’ health.
Suppress Algae Growth
When lighting, nutrient level, and filtration are balanced, proper CO2 helps to suppress algae growth.
Water Circulation
If you use reactor-style or inline diffusers, they will improve the water circulation.
CO2 Atomizer Vs. Diffuser
CO2 Atomizer Vs. Diffuser
CO2 helps in faster plant growth as it is required during photosynthesis. You can provide it with two types of equipment, i.e., CO2 atomizer and CO2 diffuser. Although both serve the same purpose, they have some differences besides the common aspects. In the following, you’ll learn about these similarities and differences.
Similarities
Purpose
Both serve the same purpose, i.e., to supply water-soluble CO2 in aquariums for healthy and faster plant growth.
Working Medium
Both use highly compressed CO2 gas cylinders to introduce CO2 into the tank.
Bubble Formation
Both produce CO2 bubbles in the tank.
Placement
With a few exceptions, both CO2 providers are placed near the bottom of the tank.
Differences
| CO2 Atomizer | CO2 Diffuser |
| It uses ceramic or nano-pores to push CO2 pressurized into the tank. | It uses ceramic discs to push the pressurized CO2 into the tank. |
| It produces fine bubbles, i.e., mist form. | It produces relatively large bubbles, i.e., a subtle form. |
| It provides high efficiency due to a slow rise. | It provides relatively less efficiency. |
| It works at high pressure, i.e., greater than 30 PSI. | It works at relatively lower pressure. |
| It produces a mist cloud in the tank. | It produces relatively subtle bubbles. |
| It clogs frequently. | It clogs less often than competitors. |
| It requires frequent cleaning. | It requires relatively fewer cleaning operations. |
| Suitable for high-tech or densely planted tanks. | Suitable for beginners and relatively less dense aquariums. |
What Is the Role of the CO2 Diffuser and CO2 Atomizer?
Both supply water-soluble CO2 in the tank.
How Do CO2 Diffusers and CO2 Atomizers Work?
Pressurized CO2 passes through a porous ceramic membrane. The membrane breaks it down into tiny water-soluble bubbles.
Why Does It Matter?
Smaller bubbles have more surface area and do well in gas exchange. This better exchange results in higher CO2 absorption, which results in healthy and faster plant growth.

hygger CO2 Diffuser Review
hygger has developed a CO2 diffuser for aquascapes and planted tanks. It is made of a steel CO2 diffuser and is available in various sizes, i.e., 25, 30, 35, and 40cm. So, it’s up to the user to buy one according to their requirements. Moreover, it also offers replaceable ceramic discs that produce fine and uniform CO2 bubbles.
Pros
- It is made of steel, which makes it durable and rust-resistant, suitable for greater than 20-gallon tanks.
- It is designed into an S-curve. This curved shape makes it fit into the tank.
- The CO2 diffuser blends with the aquascape due to its slim design.
- It is highly durable due to its steel body and produces fine bubbles. These bubbles offer 24 to 48 hours of soaking.
- It offers consistent dispersion across the porous ceramic disc.
- You can replace a ceramic disc in case of malfunction.
- It is easy to install in the tank, and it rests at the bottom of the tank, which offers better absorption of CO2.
Cons
- It produces relatively large bubble sizes.
- A piece reported rust after 2 weeks of usage. However, this is not a universal problem.
- Its porous disc usually remains clogged while working with fine substrates, e.g., sand and fish-disturbed bottom.
Final Advice
If you have a gravel or coarse substrate planted tank, it’s suitable to buy a hygger CO2 diffuser.
Final Words
CO2 diffuser is a blessing for your planted tanks. It’ll increase the plant growth rate, suppress the algae growth, and improve the overall tank’s health. CO2 diffusers do well for beginners and lightly planted tanks. However, if you have a high-tech, densely planted tank, use a CO2 atomizer. However, it requires frequent cleaning. Install a hygger CO2 diffuser for your coarse-bottom planted tanks.
