BAOSHISHAN Aquarium Co2 System 2L, Upgraded External Threaded CO2 System Generator with Double Switch Solenoid Valve, Co2 Aquarium Kit for Aquarium Plants

The tank is quite good and it works nicely (so far, less than a week from the first launch). However, its solenoid valve doesn’t do anything at all: whether or not it is on (the green indicator LED on), the gas is bubbling with the same rate. UPDATE: after I had disassembled the valve (found a pice of advice on a specialized forum), stared at its guts menacingly and then assembled it again, it changed its mind and started to work. I am not sure whether it was a stuck spring or my threatening stare, but… so far so good.

works great has been running for over three months for six hrs a day on timer meter still shows high in green area

It worked perfectly at first, and I had no issues until about a week ago when it suddenly stopped releasing CO2. I emptied and refilled the system to ensure it wasn't just out of gas, and I confirmed there are no leaks. Despite this, it still won't release any CO2.

Súper bien

Received product and worked doesn’t leak but the magnetic Solinoid did not work so I can’t say the product worked right, the paining on the valves was also scratched and I did not like that seeing as this is a new product I am going to let the gas finish and return it was not happy with what I received
