Co2 tank - How long should it last.

[Booswalia]

How often would you need to fill a 10 lb Co2 tank on a 25 gallon aquarium?

I only got mine about 3 weeks ago and it's in the red, "order more" area all ready. Is that normal?

well....

I usually get about 3 months out of my 5lb bottle. So I'd guess you'd probably get about the same, maybe a tad less. Check for leaks.

That's definitely not normal. I'd recommend a thorough check for leaks on all fittings.

My 10 lb. tank lasted almost a year (357 days) at a rate of 1 - 1.5 bubbles per second.

If Booswalia has twice as much C02 as you do, how do you figure he/she would "get about the same, maybe a tad less" than what you get?

Sorry... I have a 10G So a 5LB bottle lasts me ~3 months therefore he has 2.5x as much water volume and 2x as much CO2. So I figured it should last roughly the same amount of time, probably a little less. Now that I think about it, there are more variables than just the bottle size and volume of water that will effect the CO2 usage. But anyway, 3 weeks is definitely not normal.

Godslayer, just because you have a bigger tank doesn’t mean you use more CO2. I have a 10 lb bottle and it lasts 7 months on my 75 gallon tank. I have it at about 1 bubble per second.

Booswalia, take some soapy water and put it over all of the connections to find the leak. You also want to make sure you have a washer where the regulator and the co2 tank connect.

Boos-mine did the same thing. Twice! I finally had to buy new air line and cut out my bubble counter. I must have had a major leak. Its been a month and my little needle on the gauge hasn't moved that I can tell.

Definatly check for leaks or buy new line. And by the way, I had siliconed around everything, turns out the air was making its own path out of the silicone.

I have a 10 lb. and it last me almost a year on a 65 gal. tank.

Thanks. I will definately have to check for leaks.

Should I just use silicone if I find one?

Depends where the like is, Maybe get a new line.
