Review: Takes the hobby to the next level. Super easy, safe, sharp and splendid. - Well I’m so glad a friend of mine who’s super experienced with planted tanks recommended this brand. Not only is this regulator way more affordable than others but the product is pure quality and comes with all the features you want with a high end regulator. Super easy to set up, twist it onto your co2 tank, push on your co2 tubing and push the other end to whatever diffuser you’re using, plug in the regulator, twist on the co2, get the bubbles per second you want and boom, or should I say done, no pun being intended. For me it was especially worth getting the pro model so that I could have the dual checks to stop any end of tank dump and protect my fish. I spent way more than the difference between regulators so why not spend a little more for the peace of mind. It’s also super aesthetically pleasing. Also, I wanted the option to be able to move the regulator around to different tanks if I wanted, particularly multiple 10 gallon grow out tanks I set up in the garage (with the families blessing lmao). This regulator lets you add modules so you can run multiple co2 lines to multiple tanks so you’re not having to get some splitter to attach onto a regulator which would just be opening yourself up to more issues rather than just getting a regulator from the start that allows you to add modules and grow into. I already moved mine from my 55 gallon to my 6 grow tanks and am just going to pick up another regulator. The only downside is you might end up with a few more tanks like me but even friends outside the hobby appreciate seeing 6 grow out tanks that end up looking like dutch style rainbows or epiphyte jungle scapes with the help of co2. I have a near embarrassing amount of houseplants but aquatic plants still blow me away. It’s definitely a game changer, both co2 and having a regulator that is jammed pack with these features. Oh and I recommend just going to your local homebrew store and picking up a 10 lb co2 tank. It looks absolutely incredible with the regulator and it lasts forever. It beats the crap out of anything else on the market both above and below it’s price point. Last thing I’ll say is to the people who are thinking about taking their first steps into co2. Do it. It takes a humble yet beautiful fish keeping hobby to a place where you and your fish are so so much happier. The sheer ease to which you’ll grow plants will make you feel unstoppable and your fish will color up, display brilliant natural behavior and you’ll just get so much more satisfaction seeing an underwater world that you just want to cozy up in or go explore. Anyway, this regulator knocked it out of the park for me. Great company, great selection and dope product. Dang didn’t mean to write so much but I’m friggin pumped.
Review: Amazing product - My dual-CO2 regulator looks nice and operates smoothly. I've been using it in my 20 gallon planted tank for about 2 years until it was damaged in a move. FZone customer service has been very helpful in assisting me. They reviewed my issue and provided several, easy to follow instructions to try and get it working again. Never did they take more than a day to respond. When those methods they suggested did not work, they were quick to offer me a replacement. Me and my aquatic plants enjoy the product, and I really appreciate the way FZone responded when I needed help. Would recommend.

## Features

- Dual stage construction & adjustable output pressure. Dual stage construction provides stable output pressure regardless of how much CO2 gas remains inside the CO2 cylinder, eliminating unpredictable catastrophes such as an end-of-tank-dump (EoTD). The output pressure is adjustable from 0-65 PSI based on customers’ different needs.
- Modular manifold block design. Two manifold blocks are included. Each block comes with its own high-precision needle valve and can be operated independently. You may use one block for one aquarium or use both for two aquariums.
- Safety and precision in mind. Our regulator has a built-in safety valve. It will open automatically to release the pressure when it exceeds 100 PSI. The integrated needle valve is precise. The CO2 output can be adjusted to as low as 1 bubble every 3 seconds.
- Solenoid runs on 12V DC instead of conventional 120V AC. This regulator adapts to 12V DC, which is more stable and consumes less power. The solenoid is safe to touch and is very quiet. This solenoid is designed to work with an automatic timer.
- Attention. Suitable for North American CO2 cylinder with CGA320 adapter! Installation tools are included.

## Questions & Answers

**Q: The needle valve isn't very good. The bubble count drifts often. Is there a way to manage this? Or change out for a better needle valve?**
A: I don’t have that problem with either of mine.   The needle valve is a secondary regulation device.  Try adjusting the primary regulator valve down. This will reduce pressure to the needle valve.

**Q: I just set up the regulator. But i see that even with the power off, bubbles are coming out of the bubble counter. Is this normal?**
A: No. That is not normal. The solenoid should shut off the flow completely. However, make sure you do not have the regulator pressure set too high. The regulator should be set to the lowest pressure that will allow bubbles to flow. Mine runs a little over 20 psi. If the pressure is set to high, the solenoid might leak.

**Q: what size wrench do i need to tighten this regulator onto the bottle of co2?**
A: I just use an adjustable monkey wrench on mine. You don’t have to tighten it incredibly tight.

**Q: would I need a stand-alone check valve when using this regulator with an inline diffuser?**
A: The manufacturer says the bubble counter has an integrated check valve. So no. But I would!

### ⭐⭐⭐⭐⭐ Best CO2 Regulator Out There
*by M***H on April 22, 2026*

I’ve had the FZONE Pro Series CO2 regulator for a while now, and as a first-time CO2 user, it was actually really easy to set up and get running. Connecting it to the tank was easy, and dialing in the bubble rate wasn’t hard either. I like how easy it is to adjust and how stable it stays once it’s set. Being able to run multiple tanks is a big plus for me since I have five tanks. Some use CO2 and some don’t, and you can definitely see the difference in plant color and growth. Overall, it is a solid and reliable CO2 regulator, and I haven’t had any issues with it. Good option if you’re new to CO2. In the photos below, the tank with the black sand and rocks is the one running CO2—that’s what it looked like when I first set it up. The tank with the corys doesn’t use CO2, and you can definitely see a difference in the plant color (even though one has tannins and the other doesn’t). The photo with my betta is a bit older since he’s passed, but it still shows how big the difference can be between tanks with and without CO2.
