CO2 leak?

Hello all

I have a question.

I've had CO2 in my tank for a week now. I have the Fluval 88g with an adapter to connect paintball tanks. The first 6 days were great. Pressure had 900 psi each day. I came home today and it read 200. Could it be that it was a loose connection? I took the tank off the CO2 release and the tank feels lighter too. I put a new tank on and it reads 900 psi again. I really tightened it this time. Could that be the issue? The one I had on wasn't that tight apparently. Also can a sporting goods store refill a 7/9 empty tank? Or should I let it run?

Thanks

The most common problem would be a leak. I would check all your connections with a bit of soapy water to locate where the leak is.

Of course, depending on how fast you are injecting the CO2, it is entirely possible that you also ran out of CO2 that quickly (though I would still first check for leaks).

As far as I know, the Fluval 88 gram cartridges are non-refillable, making them an expensive option for pressurized CO2.

Hi LCieParagon,
I also have the Fluval 88,still in the box,as I'm waiting
for my tank to finish fishless cycle.I would really be interested in aquiring
a paintball tank adaptor that would fit the Fluval 88.I did not know such adaptors existed.Would you kindly post the type of adaptor you are using?Possibly
a link where you bought it.I would greatly appreciate it.
Just had a thought,you may want to use PTFE(plumber's tape),also teflon
tape.Apply clockwise to the threads of adaptor and threads of paintball tank.You will definitely get a better seal.
cheers

I got this unit before I purchased my pressurized co2. The cartridge alone cost $14 to buy and only lasted me 3 days (due to leak).

I did some research on this unit, and it seems that if you use Teflon tape, it helps greatly. All in all, the cartridges are suppose to last about 2-3 months, depending on how much co2 you are pumping into the tank.

If you have the money, I would def. invest in a pressurized co2 instead. $20 to fill a 5lbs tank, can last anywhere from 6 months to a year.

The adapter I got is this: works great
I just need to put Teflon tape on it. It's leaking like crazy.

So it didn't seem like there were any leaks, but I put Teflon tape around the threads of both the adapter and the paintball tank. I used soapy water to test for leaks afterwards and seems like nothing so we'll see if this works. If I run at 4 bps (bubbles per second) how long should I expect it to last running 24/7?
