FZONE Aquarium Co2 Regulator Aquarium DC Solenoid Bubble Counter and Check Valve Plant Grow DIY CO2 System W21.8 Side Open Cylinder

Brilliant regulator. Does what it should. No leaks that I can see. Easy to set up and get co2 running on any tank.

Working well just what is needed

Fitted straight on to a standard CO2 bottle. Does the job.

I recently upgraded to this FZONE regulator, and I’m genuinely impressed! If you are looking for a high-quality CO2 setup but don't want to pay double for a "luxury" brand name, this is the one to get. Build Quality: Right out of the box, it feels incredibly solid. It has a heavy, professional-grade aluminum body and the gauges are clear and easy to read. It doesn’t feel like a "budget" tool at all. Accuracy & Performance: The needle valve is surprisingly precise. I was able to dial it down to exactly 1 bubble every 3 seconds with zero "drift" over time. The 12V DC solenoid is silent and stays cool to the touch, which is a huge plus. Ease of Use: It comes with everything you need—tools, extra O-rings, and a clear manual. Setup took me less than 10 minutes. Customer Support: I had a small question about the solenoid during installation, and the FZONE team got back to me almost immediately. Their support is top-tier and they clearly stand by their product. Bottom Line: Amazing value. It’s rare to find this level of accuracy and build quality at this price point. Highly recommended!

Valve stopped working after a year and a half.

Bought this product just over 12 months ago and had a couple of problems with the cable and the solenoid , i replaced the cable a couple of times , decided to complain to F Zone , and got to say the acted great , gave me chance to buy the new upgraded solenoid and wiring at a very reduced price , (unfortunately the 12 moth guarantee had run out ) i have now fitted these and got to say a far more satisfactory product a lot better all round , all working great now

Had used 3 fzone regulators, from this model to the more expensive 2 valve one. The team at fzone are very kind and always ready to help. I had a missing silicone seal that they happily sent to me! Would definitely recommend this brand!

The solenoid wasn't working out of the box. Some investigation revealed that the +ve wire wasn't connected and the -ve was very loose. The insulation on one wire was damaged and the conductors were visible. After fixing these issues and a few on off cycles the unit seems to be working well. This regulator appears to be identical to those sold by specialist Co2 websites for twice the price so is great value for money if you can get it working.

Bon détendeur pour un prix abordable

fits perfect

Bel appareil mais dommage que la notice ne soit qu'en anglais.

Buyer beware. This regulator solenoid does not shut off CO2. Soon as the product arrived, I read the instructions and installed the regulator on my 5lb CO2 tank. Right out the box, the solenoid was faulty and does not shut off the CO2. I then waited for over 4 hours to see if the bubbles in the bubble counter would stop. It did not. I then tried uninstalling the regulator and double checking my fittings. That did not solve the problem. I have to manually turn off the bubble counter for the bubbles to stop. I did a leak test. There were no leaks. Since my aquarium is still cycling, I have no livestock except for plants. Should I continue to use this regulator, IT WILL KILL MY LIVESTOCK. The instructions are very basic and provide no problem solving. There are some grammatical errors in the instructions and the instructions provide no pictures for reference. There is an Allen Key provided but no instructions on how or where to use this tool. Obviously, the durability of this product is simply not there. The accuracy, it may be accurate but it is very difficult to determine since the solenoid is faulty right out the box. The fit is perfect. Sadly, there are videos and reviews from others that have the same issue. Since some have this problem while others do not, you purchase this product on a gamble that perhaps yours may work. *****Update******* Change 1 star to 5 star. I was able to find a YouTube video by FZone Studios that shows how to take apart the solenoid to adjust the spring. Once I followed what the video instructed, the solenoid now works perfectly. What the video recommends is to take apart the solenoid, check for dirt/dust, unscrew the 2 screws to release the plate, then check the spring and stretch the spring a little bit. Reinstall the plate and solenoid and test to see if the solenoid shuts off the CO2. Once I did this, the CO2 shuts off within 5-10 minutes as the seller stated. The product works perfectly now.

Lo tengo varios días, funciona bien. Se oye la válvula cuando cierra y abre. Cuando está cerrada no deja pasar nada de co2, cosa q en algunos comentarios decían q si se les escaba, a mi x lo menos no deja pasar nada. De momento estoy contento, a ver si dura. X el precio está muy bien
