FZ-0100

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.

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)

Love the regulator from Fzone . Been using this product for some time now and I’m completely satisfied with the quality and the performance I’ve received . I would recommend this product to anyone wanting to add co2 into their aquariums !!

A good value for the dollar. I couldn't be happier with my purchase! The positives: -The adjustable valve allows me to adjust the flow of gas -The valves are accurate enough -The solinoid functions -Doesn't leak The negatives: -The seal where it connects to the tank likes to fall out. Maybe grease it? -The stock PSU is terrible but I got one that works now so that's a win in my book! Could you do better? Sure. For the price? Just buy this!

Didn't work right out of the box. Cheap Chinese crap. Do not waste your money. Buy a Milwaukee aquarium regulator

I purchased a single stage large gauges regulator two years ago. It has functioned perfectly. I recently contacted their customer support with questions about gaskets. They responded the very next day, and solved my problems. The regulator is well built and easy to use. I highly recommend it and it won't break the bank.

Using this regulator with a 5lb tank for my 30 gallon aquarium. So far, it seems excellent. I used a small amount of thread tape on the main connection, the rest was all sealed fine. The unit is incredibly simple to use, just plug n play, no assembly required. Some people have mentioned the solenoid gets stuck after the first on/off cycle. So far i have not had that issue, ive tested it multiple times today. The solenoid is quiet too. It clicks when going on/off, but there is no hum as I have heard some solenoids will do. I will say, the solenoid is not cool to the touch as advertised. It isnt dangerously hot afaik, but certainly not cool. The needle valve is easy to adjust and i had things dialed in within seconds. The unit looks and feels well built. I say its an excellent product for the price point. If I havent updated this post, then it’s still working!

Works as intended. Great price for what you get! Please please please use plumbing tape, and not just a little bit of it. Use a good amount. The better you protect the Male threads when screwing everything together, the more of a chance everything is gonna work out to NO leak at all to very unnoticeable leakage! Tip: Everything with a male thread, use the plumbing tape!! Regulator male adapter, co2 tank, and even the bubble counter that comes with it! Be careful on how you use this thing. Start turning one object and you might accidentally start losing something else. Use two hands. And if need to. Get pliers to help hold or tighten. It worked perfectly straight out of the box as is for a 20oz paintball tank from dicks sporting goods. ** You CAN'T adjust the amount of psi this regulator releases to you're diffuser.** THE ONLY THING YOU CAN ADJUST ON THIS REGULATOR is the circular flow valve to the bubble counter attached to this regulator for bubblesper second method. The psi should be about 50psi to 64psi [THE RIGHT GAUGE closest to the bubble counter in picture] The bubble counter can be removed. BUT once again you could be creating another problem somewhere else on the system. In my co2 system I've taken off only the top part and plexiglass of the bubble counter, to slip on the air tubing directly to the regulator, thus bypassing their own cheap bubble counter to my own custom made bubble counter for multiple tank set up. I hope this helps someone that is new to the hobby and has no guidance but only YouTube, that sometimes doesn't explain or show enough oh how to.. Good luck - & - No complaining
