ZRDR CO2 Regulator Aquarium 12V DC CO2 Solenoid Pressure Adjustable, Bubble Counter with Check Valve, Aquarium Co2 System CGA320 Side Open Cylinder…

I like how easy it was to put together and I like that I can fill the bubble counter with a syringe. It’s very easy to operate. It’s a good purchase. Definitely recommend this over any co2 bag or bucket that takes days to start working. And you don’t know if they stopped working. This clearly shows if it’s working and I control how much I want when I want. Refills are cheaper than one co2 bucket and a refill on a tank last me more than a year. Seriously this is way to go.

Good product Easy to use and install

I have zero issues with this unit. Works perfectly! High quality parts and I can tell this will last me a long time.

It’s ok for a short amount of time or to fill in as a back up. I don’t feel like it’s trustworthy.

I purchased this regulator for my planted aquarium, and it has been performing well. The setup was straightforward, and I appreciate the dual pressure gauges that make monitoring easy. The solenoid operates quietly and maintains a consistent flow. The bubble counter is accurate and simple to fill using the provided syringe. I did experience a slight leak when unplugging the unit, but it wasn't significant enough to be bothersome. Overall, this regulator offers great value for its price and is a solid choice for hobbyists seeking an efficient system.
