I wanted something small and easy (being a beginner with high-tech) just to give it a try and this system didn’t disappoint. The price was right and the setup was super easy. It comes with a bubble counter but I wanted a solenoid to turn it off at night. So I got this additionally. I also got the CO2 diffuser. So far so good. It looks very sturdy for its size. All quality metal no plastic. And it is so small I could easily put it in my bookshelf. See the postcard next to it in one of my photos. I already got another one for my other tank! Review: Great Nano CO2 System - This CO2 system is perfect for my 11 gallon tank! I set it up along with their solenoid valve! It’s easy to set up and a good value! My plants are happy! ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.3 out of 5 stars 160 Reviews | ## Images ![FZONE Desktop Aquarium CO2 System,45g CO2 Cartridge,5/8" & 3/8" Compatible | Space-saving,Lasts 20–50 Days,Quick & Easy Setup,Compact,Portable,Lightweigh,Precision Bubble Control,For Nano Planted tanks - Image 1](https://m.media-amazon.com/images/I/51N4sSf-ABL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing little system *by A***N on July 18, 2026* I just set up this awesome little CO2 system for my 23G community tank.

I already got another one for my other tank! ### ⭐⭐⭐⭐⭐ Great Nano CO2 System *by G***S on July 20, 2026* This CO2 system is perfect for my 11 gallon tank! I set it up along with their solenoid valve! It’s easy to set up and a good value! My plants are happy! ### ⭐⭐⭐⭐⭐ Beautiful, perfect, affordable and easy *by S***. on June 26, 2025* 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! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/729865290-fzone-desktop-aquarium-co2-system-45g-co2-cartridge-5-8](https://www.desertcart.sg/products/729865290-fzone-desktop-aquarium-co2-system-45g-co2-cartridge-5-8) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-30*
