    Great iteam make CO2 easy
  

*by C***N on Reviewed in the United States on January 21, 2019*

I bought this aquarium co2 regulator used to replace other brands, installation is very simple, finish it in two minutes.Power on, I can see the red indicator light in the solenoid valve, then open the co2 cylinder valve, daul gauge show the pressure inside the bottle and the working pressure, adjust the outlet speed through the needle valve, Precision fine-tuning valve is very sensitive and easy to adjust,and it is quickly adjusted to 3 bubbles per second. After two weeks, everything is fine now , no any leak, the solenoid valve works very well, it is quiet, and it is heatless,bubble counter is good. The seller told me that the problem that needs to be noticed is that the middle knob is not used to adjust the pressure,It is a safety valve. It is generally not used,SO I won't rotate it. I think that’s OK. The speed of the air outlet can be adjusted very well by the fine adjustment valve. In summary, this co2 regulator is very good,my plant grow well, I like it very much.

    Wow. Glad I gambled.
  

*by G***R on Reviewed in the United States on March 23, 2019*

After doing hours of research on CO2 regulators, I couldn’t justify spending $200 on a regulator no matter which way I went. I scrolled through amazon until I found this guy and it had one review. For the price, I was willing to gamble. I’m soooo glad I did. This thing can be adjusted to below one bubble per second and brought my CO2 levels from unacceptable to great in two days. I highly recommend this product to anyone just getting into the CO2 aquarium injection game.

    Explosive regulator Safety hazard
  

*by J***. on Reviewed in the United States on March 23, 2019*

Well I have to change my review after using it for a little more than a month. Last night in the middle of the night it blew all of its guts. By that I mean the pressure adjustment knob blew out and shot across the room taking the pressure valve with it. In doing so it destroyed the  solenoid valve so now it’s completely junk and not useable at all. For your safety do not buy this. If it would have happened during the day the pressure valve would have hit me right in the leg and with that much pressure I’m sure it could have busted bone because where it sits under my work desk.
