Review: Beautiful, perfect, affordable and easy - I bought this for my smaller 2 1/2 gallon tank and it’s perfect for that. It’s very beautiful very well-made it’s made for smaller aquariums and as long as you don’t do the bubble count too high it should last you for quite some time at least a month maybe two if you do one bubble a second but for smaller tanks, you might get away with even longer. FZone is a great company. I have many of their products and I love them. Super affordable and well made products that come with the best customer service. They are fast and responsive if you have any issues just email them and they will work with you to diagnose your issue and if you need a replacement or a new part they will send it out right away. I can’t say enough good things about FZone. This device makes absolutely no noise and it is very easy to assemble. A quick note- before you attach the CO2 tank make sure the white plastic gasket is in place. Mine came with the gasket in a baggy and the instructions didn’t mention installing it. I think it may have been an oversight in production but it happens. Other than that make sure you use CO2 tubing because regular airline tubing will not work because of the pressure of CO2. Also buy a drop checker device so you know how much co2 is in the water. Start slow and keep an eye out for fish gasping at the surface, thats a sign they are getting too much co2. It’s recommended to also keep an airstone attached to an airpump to keep oxygen in the water. Don’t be intimidated just do some research and you’ll get the most beautiful results with your plants and the fish thrive when the plants thrive. I would recommend this product for any nano aquatic enthusiast. I would recommend buying a nano diffuser as well. Thank you again FZone for another great product!
Review: Great product! Don’t forget to insert the gasket! - I love this thing. Only one key piece of info missing from the instructions: the little white plastic piece (there is also a thicker red one) is a gasket that goes between the regulator and the tank. Make sure you insert that piece in there before you screw the tank on. Currently running this on my 10G rimless tank, no issues whatsoever. Easily keeps the drop checker a healthy emerald green, I messed around with the adjustment knob a bit and found it fairly easy to get this thing down as low as 1 bubble every 6 seconds. I may purchase another one for my 2.5G micro tank. I love this little thing, it’s so easy to change the tanks out and at a lower flow rate, should last a while. You can also use the smaller co2 cylinders available for airsoft toys by threading on the included brass adapter.

## Features

- Compact and Portable CO2 System: For small or desktop aquariums, standard large CO2 tanks can be bulky and impractical. This portable mini CO2 regulator is just 9.84 inches tall and 1.96 inches wide, making it a perfect fit for small spaces. Its slim design is easy to hold with one hand, offering both convenience and ease of use.
- Compatible with 5/8" and 3/8" CO2 Cartridges Threads: This CO2 regulator aquarium fits standard 5/8" threaded cylinders and comes with a 3/8" adapter, providing perfect compatibility with different cylinder sizes. No need to purchase additional converters or adapters, making it easy to use while saving you time and money.
- Long-Lasting High-Density：Liquid CO2’s higher density enables a compact design with extended usage. Through internal testing, we found that each bubble consumes only 0.03 ml of CO2. The mini CO2 regulator kit equipped with a 45g cartridge, can last up to 50 days at 1 BPS, on an 8-hour daily schedule.
- Effortless Setup ：Disposable CO2 cartridges eliminate the need for frequent refills, ensuring quick setup and low maintenance. The Quick-Connect feature allows instant CO2 tubing installation without rotating the pipe—setup is done in seconds.
- Safety and Reliability： This CO2 regulator system features high-strength aluminum,a seamless design, and precision sealing to ensure durability and prevent leaks. The single-use design eliminates refilling, providing safety and convenience, making it perfect for indoor use.

### ⭐⭐⭐⭐⭐ Great For Planted Tanks! Get it NOW
*by R***U on January 20, 2026*

WOW! This is a great little setup. I had a larger F-Zone reactor kit and this works just as good as the big guys. THe value for the money is amazing as you can get new cartridges for cheap. No noise to speak of, I added it to an inline diffuser and it's crushing it! after jus about a week my tank has perked up immensely, beautiful greens and looks like more root growth and spreading. Well made, super durable and seems to be super well made. If you want an easy solution for CO2 I would go with this all day long!
