desertcart.com : FZONE Aquarium Co2 Regulator DC Solenoid with Bubble Counter and Check Valve Plant Grow DIY CO2 System CGA320 Side Open Cylinder : Pet Supplies

Review: Buyer be aware******Update******* - 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.
Review: Works Well monthsbin - This works really well on a keg fridge tank that I wasn't using anymore. I would caution to start very low to get the bubble rate correct as this one seems to put more CO2 in the water than those DIY kits that use baking soda and citric acid. This is so much easier, cleaner, and more cost effective long term as well.

A: Sorry we don't have that.

### ⭐⭐⭐⭐⭐ Solid Quality, No Leaks, Separate Tubing Needed
*by R***. on June 13, 2025*

I was honestly expecting issues based on some of the reviews—lots of people mentioned leaks—but that hasn’t been my experience at all. I’ve had this FZONE CO2 regulator running on my planted tank for a week now and the seal’s been completely solid. No hissing, no pressure loss, nothing. It’s holding a stable output and the fine control on the needle valve is better than I expected, especially for dialing in low bubble rates. One thing that caught me off guard is that it doesn’t come with any CO2-proof tubing. That feels like a bit of a miss. I already had some on hand from a previous setup, but if this is your first regulator, just know you’ll need to buy that separately. Not a dealbreaker, but something I wish was clearer upfront. All in all, if you’re careful with the setup and you use proper tubing, this regulator delivers. Solid build, no leaks, smooth output. I’d use it again on another tank without hesitation. Pros: – No leaks – Holds pressure well, even at low bubble rates – Solid build quality and smooth needle valve adjustment -Nice design Cons: – Doesn’t include CO2-proof tubing – Instructions could be clearer for beginners, including timing (be sure to turn off your co2 when the lights are off)
