Aquarium CO2 Regulator, Big Dual Gauges Display,12V DC Solenoid with Bubble Counter and Check Valve, Carbon Dioxide Regulator Fits US Standard CGA320 CO2 Cylinder

Setting up a C02 system can cost a lot. I was really glad to find a regulator for such a great price. So far so good, everything is working as expected and my plants are getting spoiled. The longevity/durability is the only thing in question, given that typically the "good" regulators cost $120 currently; This feels solid, it's mostly metal (plastic housing on solenoid and the bubble counter is acrylic).Setup was really easy; ymmv but i had zero issues with leaking on the first try, which never happens to me, so I think we have a winner here.

After installing I connected to a Milwaukee ph controller and the solenoid clicks constantly and doesn’t stop the co2. I tested the ph controller and it does turn the outlet on and off like it’s supposed to. So it’s the solenoid

This is a good regulator but has some flaws. After mounting it on the CO2 tank for the second time it started leaking from the tank gauge, so I fixed it with a permanent threadlocker. Other flaw is that after two weeks of work I realized that the tank gauge doesn't go below 400 psi even if I dismount it from the tank. That's reasonable for such a cheap product. I used to see many gauges that can't withstand more than 800 psi even if their pressure range is up to 2000 psi. Overall, I love the size. It's compact and nice.

I don't leave feedback often. However, as a novice at adding CO2 to an aquarium, this regulator was an awesome purchase. It is well made and has most of the components you need to begin adding CO2. Great buy!

Aunque el regulador funciona, tuve que ajustarle uno de los manómetros, porque al poner el regulador en el tanque y abrir el flujo de Co2, el Co2 se escapaba por la rosca entre el manómetro y el regulador. Lo soque y la fuga se solucionó, pero, el manómetro quedó torcido.

Works great for Calcium Reactor in aquarium

It seems like I"m having the same problem many others are having. On my days off, I was hearing a hissing sound that I thought was coming from outside. After awhile, I noticed it wasn't coming from outside but near my aquarium. That's when I found the leak at the gauge. Just like in the video. I tightened it up but it started again less than a week later. I took it apart and installed a gasket and tape. Same issue. I was going to order another one thinking I just got a bad device. Then I saw the reviews.NOPE!!! I'll save my money.

I actually got this to replace my f-zone mini that exploded on me and so far this has been much better and way more controllable. Very easy to fine tune and ive had no problems with it although it is very lightly used in my particular application which is a 6 gallon aquascaped high tech tank.
