Features
- Thicker and last longer! Fzone's DIY CO2 bottles last longer and are thicker than average! With a strong interior wall that can hold more raw materials, our bottles are made of 1.5mm thick SUS304 graded stainless steel, 25% thicker than competitors. The Fzone co2 kit aquarium can withstand a max 80kg/cm2 pressure and generates CO2 gas for 1 month at 1bps for 8 hours a day when filled with 300-400g raw materials. Get a longer-lasting and more efficient CO2 solution with Fzone!
- Professional DIY kit -- A complete system in 2.5L size bottle, that includes SUS304 stainless bottle, regulator, precision needle valve, and easily adjustable bubble counter. Safety valve will open automatically when the inside pressure exceeds the safety threshold.
- High precision--Needle valve with bubble counter. Aquarium specific needle valve provides accurate fine-tuning. Steady 1 bps is achievable. Bubble counter with check valve built-in. It stops water from back flowing into your CO2 tank (protects your CO2 tanks from rust and corrosion)
- 12V DC Instead of AC Power: having the solenoid on a timer, you can specify when you want CO2 injection on and for how long
- Attentions: the required powders to generate CO2 gas are not included; you will need purchase the citric acid and sodium bicarbonate powders separately.
- Customer Service Team:Fzone will offer a round-the-clock service, and you can reach out to us at any time for any product-related concerns.

Pattern Name: 2.5L Kits with Solenoid
No seal problems, all parts there, instructions are mostly good. If you dont have a scale, you'll need to do a little math. I added 13.8 Tablespoons Baking Soda, and 8.3 Tablespoons Citric Acid with my 300ML water and it seems to be working out... but again do your own math and make sure do NOT take my word for it. It's been a few weeks and my plants seem happy and my fish are alive so those measurements haven't killed my 29G just yet... Anyways, the setup seems ideal and is decent price as far as I can tell. It does the job well, and hasn't failed me yet. Seems like it's decently made so I'm happy with my purchace. Would buy from this seller again. On a final note... buy a CO2 drop checker. I did some math and figured 1 bubble per 2 seconds was good.... now I'm using 4 bubbles per 1 second. It will help you figure out how much to be adding to your tank and save you mental stress trying to guess. Just take it SLOW and figure out what rate gets your checker green fastest and keeps it green without going into the yellow (danger) zone.

I bought this for my small 7g aquarium. Original plan was to keep it without co2 because I was out of spare 5lb cylinders and regulator and I needed something small to tuck away. I have used fermentation co2 when if started in the hobby but it never generates enough pressure to use a decent diffuser. This system is great. It arrived next day. I was able to put it in service same day and it was putting out 50psi which is more than adequate for any diffuser. Assembly was easy. Quality of materials is very good. Came with spare orings, co2 tubing, bubble counter, diffuser and a u-tube. Also had a filter which is very essential to keep the regulator out of any issues form the acidic mix. Most of these systems don’t have a good solenoid to run on a timer but I have used fzone regulator and this solenoid is just as good. The bubble counter is solid with not backflow issues. The needle valve is good enough for my needs. Was able to dial it to little under a bubble per second. Also like the 2 guages to show you cylinder pressure and working pressure, which will allow me to know when it’s time to refill the system. It’s been 4 days and the pressure is holding steady and the plants are definitely enjoying it. Would definitely recommend this system to anyone.

Fzone has fantastic customer support (thank you Cheryl). I was missing the white piece on my filter and they sent me a new filter. I have used an fzone regulator on a paintball tank previously, but I had a stroke, and it's no longer possible for me to go get CO2. Therefore, I looked for a CO2 generator and was happy to find that fzone had this one Because of my previous familiarity with using CO2, despite the horrible instructions, it was quite easy to get set up and get started. This unit came with a solenoid which works perfectly. I have it on a timer to turn on in the morning and shut off at night. I replaced the diffuser with one from clscea (stainless steel, widen hook 25cm) which works much better, especially for rimmed tanks. The supplied funnel's base is too narrow to be of real use (fzone please replace this). This unit no leaks, it's looks great, runs quietly, gives me great value for money, and I have to trim my stem plants more often now and my plants look fantastic Fzone makes great products and I will buy from them again.

The media could not be loaded. It’s a pretty solid system. The needle valve is a little sensitive for my taste. It’s not bad but it could be a little better. The materials are all high quality. The system is running well without any issues. The diffuser is a little on the low end. The bubbles are a mixture of good micro bubbles and some larger bubbles. I would recommend getting another one if you want tiny bubbles all around. It’s solid though as none of the bubbles were large. The system was easy to set up. They say use 200 grams of citric acid and 200 of baking soda. Chemistry says you need 200 grams citric acid and 260 grams of baking soda to get a perfect consumption in the chemical reaction based on the mole weight of each. I went with science to avoid having a lot of left over matter when the tank needs to be refilled. You can avoid the crust or unused citric acid some complained about in the tank this way as all the citric acid will be used in the reaction. That’s a pretty minor issue though. All in all, it’s a good build and quality materials. I got some pearling of my plants day one. The price isn’t bad given everything. I would have given 5 stars for a slightly better needle valve and a slightly better diffuser but it’s a good quality system. Update: Day two my diffuser is even worse. The plate doesn’t seem attached and all the co2 is just leaking out the edge of the diffuser. Definitely a four star product because the diffuser is worthless. But that’s my only complaint. Solenoid runs cool, everything else works great.

I recently purchased the Fzone 2.5 L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit, and I must say, I'm quite impressed with it. This kit includes everything you need to start adding CO2 to your planted tank, making it very convenient. The quality of the components is top-notch, and you can see that the CO2 canister walls are really thick, which gives me peace of mind knowing it's safe to use and won't explode like some DIY CO2 systems using yeast. The instructions provided were incredibly clear and easy to follow, making the setup a breeze. I'm currently using it with my new 7-gallon cube, and it's performing excellently. While I wouldn't recommend this CO2 system for larger tanks, as I prefer pressurized CO2 with a regulator for those, it's perfect for smaller tanks like mine. What I also appreciate is that Fzone is a trusted brand known for its solid reputation and great after-sale support. Knowing this, I feel even more confident about my purchase. I'm very satisfied with the Fzone 2.5 L Aquarium CO2 Generator System and would recommend it to anyone looking to enhance their planted tank with CO2 injection.
