Most aquascapes today are equipped with water filtration devices. Additionally, CO2 generation devices must also be installed. This helps aquatic species in the tank thrive at their best. Let’s explore 5 specialized CO2 devices for aquascaping together.aquaplantshub.com.
Notes when using the aquascaping CO2 system
To ensure aquatic plants in the tank grow well, it is essential to guarantee that photosynthesis occurs. This process requires two key factors: light and CO2. Therefore, in addition to having a suitable lighting system, aquascaping enthusiasts pay great attention to the CO2 generation system. Currently, CO2 systems are widely used. To ensure the system operates effectively, pay attention to the following:
- Install components according to the correct procedure, ensuring standards and safety.
- Do not place devices in high-temperature areas or high positions that can create friction.
- Research and accurately measure the appropriate amount of CO2 to use for the aquascape.
- Be sure to observe and monitor to adjust the CO2 levels when there is an excess or deficiency.
5 popular specialized CO2 devices today
A complete CO2 system will consist of 5 essential devices. Installing the full set of 5 devices includes: CO2 cylinder, one-way valve, bubble counter, CO2 mixer, and connecting hoses. You can easily find these CO2 devices at aquascaping equipment stores.
2kg CO2 cylinder with brass valve
Reference price: 600,000 VND

CO2 cylinders at retail stores typically range from 2kg to 6kg. They include a pressure regulator and a main valve designed to connect with each other. There are various materials used for CO2 cylinder valves, but the most common are brass and stainless steel. The 2kg CO2 cylinder is often the most popular choice due to its compact design, making it very suitable for indoor aquascapes. Its moderate weight allows for easy adjustment.
One-way valve
Reference price: 10,000 VND – 50,000 VND

This is an essential tool in the CO2 device system. Its main function is to allow CO2 from the cylinder to flow directly to the tank while preventing the CO2 gas from flowing back. This avoids blockages or poor ventilation. There are many types of one-way valves on the market with various designs. The materials used are also diverse: plastic, glass, stainless steel, etc. Stainless steel products are often preferred for their durability. Additionally, the price of valves varies depending on the material used.
Glass CO2 bubble counter
Reference price: 60,000 VND – 150,000 VND

The amount of CO2 you introduce into the tank needs to be measured and considered carefully. Therefore, the CO2 bubble counter is a very useful tool for this. Adjusting the amount of gas entering the tank becomes much easier. Depending on the size of the aquascape, the number of bubbles will vary. The smaller the tank, the fewer CO2 bubbles, and vice versa. Bubble counters also come in a variety of designs, depending on individual preferences.
External CO2 mixer
Reference price: 270,000 VND – 450,000 VND
Next in the CO2 device system for aquascaping is the CO2 mixer. We introduce the external CO2 mixer, which is very convenient for beginners. The external CO2 mixer with a 16mm pipe is suitable in terms of quality and price. The biggest benefit of using a mixer is that it helps the CO2 gas pumped in dissolve into the water more easily, achieving maximum effectiveness in creating natural CO2 for the aquascape.
CO2 connecting hose
Reference price: 50,000 VND
Finally, the connecting hose links the devices together to transport CO2 from the cylinder to the tank. There are many connecting products made of flexible plastic or stainless steel tubing. However, for ease of installation and use, flexible hoses are more commonly used.
This review of the top 5 specialized CO2 devices for aquascaping concludes here. Thank you for your interest and following along. We hope you gain a lot of knowledge from our shared articles.
