Aquarium CO2 Regulator with 12 DC Solenoid-Big Dual Gauge Display Bubble Counter,Check Valve Fits Standard US Tanks-Accurate and Easy to Adjust Flow Meter

I buy this to replace a Co2 Milwaukee regulator that brake 3 time on me (solenoid, low-pressure & main diaphragm). I wasn’t sure of the one high pressure gage setup. Install & set in minute with the good visual simple instruction. The complete construction is solid and feel high quality. The high pressure is small but readable (increment of 100psi). No leak and the needle valve seem even better than the Milwaukee reg. Price is excellent and the product is perfect for precise injection of CO2. Thanks for this great product. The small metal wrench to secure it to the tank is a nice touch and perfect to do the job also one o-ring is already install on the reg. and they even sen you a spare. Sad Amazon do not have 6 stars. I will comme back in few months to review again.Update 1:— Bubble count is steady when the solenoid open in the morning— Solenoid is warm not hot if I compare with my Milwaukee, you hear the normal click

Works real well for CO2 injection. The adjustment could be a little finer, but it seems solid. Been using it for a few weeks now and so far so good.

I have two of these. The first one was purchased in December 2020 and is already done for. It has developed a gushing leak where the pressure gauge attaches to the CO2 tank. I have been so busy over the last couple of weeks that there is no telling how long this has been a problem.The second is still functioning, but I will be keeping a close eye on it.You know, if this was an item that gets constant handling and moving, one would expect wear and tear. But for a CO2 regulator that sits protected inside of an aquarium stand and only gets touched a couple of time a year...Buy something else.

First one I ordered had a non functional solenoid so it stayed on day and night. I filed a return and the new one arrived a week later. Second one had a broken drop check glass tube. I moved the glass tube from the original to the replacement and everything looks and works great.This model uses an o ring instead of a plastic gasket at the tank so it saves a lot of hassle. No leaks and the solenoid works great turning it on and off.

I ordered this co2 regulator to replace the old one on my plant aquarium. This regulator worked flawlessly with my plants and fishes. It seemed to maintain a stable flow, and it came with O rings I needed to make the change from the old one. Everything appears in high quality. Great for use.

the product works great... even though it doesn't have a regulator on it ~ controls the pressure going to the line~ it does work really well for my aquarium.

Bought in February, dead in November. Worked perfectly fine before it suddenly decided to stop working. The problem is the solenoid. It's clicking when turning on, but not actually opening to allow co2 to flow through from the tank. This happened to me one time before it broke, and I wiggled the solenoid cord and it opened right up. But won't work now. So you get what you pay for. Easy to set up, easy to operate, easy to die.

When I saw the product, I didn’t realize that 1) it doesn’t fit my 20 oz paintball tank and 2) if I use it with my paintball tank, the bubble counter that comes with it will stay horizontal instead of being vertical because it is designed for big co2 tanks. I bought an paintball tank adapter from aquatek which worked very well. And to solve my second problem, I left the bubble counter without water and just attach an old bubble counter which worked perfectly. I was traumatized from using another regulator that I bought which was leaking all over the unit. I was scared that this would do the same because price was cheaper but I am very happy that it worked.
