It has been debated in the past... I think the conclusion is that there is an oil mixed in with the C02 to lube the gun when it fires(I could be wrong)... Oil and planted tanks hence dont mix...

The problem is finding a way to get the CO2 from the cylinder to the tank. I'm not sure if you can even find a regulator that will fit a paintball cylinder. And then there is the problem of how long it's going to last.

From what I understand ADA makes a fitting for these small tanks because the norm in Asia is 15gal or something to that effect.. check it out over at AB

You don't. If you can find that little regulator the price will scare the crap out of you. As I recall the regulator alone was somewhere in the neighborhood of $150. That's pretty much a regular sized CO2 system price.

paintball CO2 is plain old CO2...I used to help a friend fill our 7.5 and 9 oz tanks back home when I played.
But yes, the problem is that CO2 tank is 20oz. depending on the size of your tank, you might be refilling it every month, instead of a couple times a year.
Plus, consider the cheapest standard regulator I found was $44, but by the time I got a bubble counter and needle valve, it was as much as a Milwaukee all in one, which can be had for $80 plus shipping.
If Rex says one for your non-standard tank is $150, I'd believe it. For that price you can get a Milwaukee all in one, and a 5lb or maybe 10lb tank.

There's a difference between DYI, and forcing objects to perform tasks they were never intended to perform.

you can use the paint ball cylinder just goto a welders store or and place that they sell nitrous oxide. Because the will also have to carry co2

The nitrous oxide comment explains a lot. The problem with the paint ball cylinder as has been explained is that you need to find a regulator for it. They are available but cost more than a full normal sized CO2 setup costs.

I believe this is very possible to do for way less than what a 5lb tank will cost. The only thing im concerned with is how long it will last. To get the CO2 to the regulator all you need to do is buy a cheap paintball remote. Found on ebay for around 25-30. This will press the pin to get the co2 out and the end of the remote has the right size to fit a standard regulator. I havent tried any of this but I play paintball and have taken my paintball remote and it is the same size as the bulk CO2 tank so im sure it will work. If anyone has tried this let me know on how long the tank is lasting.

I can get a 5lb CO2 tank around here for $60 Canadian... So Around $40 US... So if you figure your cost of the adaptor, your only looking at an extra $10... Not a big savings for a considerably smaller bottle that you will be filling monthly.

no matter how many times someone will try to drudge up this post...the fact remains that using a $40 20oz paintball tank will never be as cheap as a 5lb setup. You have to buy that adapter, which I've seen priced from $40 up to $80...in addition to EVERYTHING else (regulator, airline, etc)

Plus the end on a paintball tank is NOT the same as a CO2 cylinder, so my local welding place wont' fill them. instead I'd have to go to a paintball store and have them fill it. last time I checked a 20oz tank was $8 to fill. my 5lb tank is $10 a fill.

Now, has the dead horse been fully beaten?

I brought this post back up because I'm looking for a mini setup.

It seems that the main reasons why not to use a paintball tank is-
1) cost of refills (co2 runs out too fast)
2) specialized refill stations.

After doing some research- i found that you can fill your own paintball tanks if you have the right tools and pay about the same amount on co2 refills.
I found this on eBay. You can use a 10 or 20# tank with a special adaptor.

Here is one that's even cheaper-
http://cgi.ebay.com/Paintball-Gun-Fi...QQcmdZViewItem

Now the main reason why I want a mini co2 set up is space. I'd like to put a paintball tank behind the tank, out of view. Its just how I want to set it up.

The only problem I'm encountering at the moment is the regulator. Since a paintball tank has different sized threads, the normal regulators we are use to wont fit them.

My question is- is there an adapter out there for a paintball tank, so I can use a standard co2 regulator?
