Hi, I have a 4kg CO2 tank and it only last for a month - month and a half. Some say it lasts for 3 months. I also shut it off during the night. Do I have a leak? My solenoid valve is not directly connected to the regulator but via an intermediate CO2 pipe with clips on the ends to prevent leaks. I did the soap and water test and there seems to be no leak.

What size aquarium are you using this cylindar on? By my calcs it is about 8.8lbs.
Some additional information that would be helpful is the CO2 levels that you are maintaining in the aquarium, what diffusion method you are using, and whether you have anything that could be causing CO2 to gas off.

It does sound like you have a leak, but to be sure I would weigh the tank empty then full to make sure it's getting a full 4kg when you have it filled. That is the likely problem if it passed a leak test.

I would agree, sounds like a leak somewhere! that should last longer than amonth or so on a 55 gallon tank, especially if your shutting it off at night. let us know if ya get it worked out! Good luck!
