Yeah that's a really nice one, but I don't see a solenoid valve on it. Still though very nice- I wonder how you'd go about getting something like that in the states?

BTW I'm getting about 8 to 10 weeks roughly on an 87 gram disposable Co2 cartridge. I run the Co2 kinda high at 1 bubble or so a second. BTW here is what is looks like. Cost to make one is anywhere from $160 to $250 depending on where you get the parts from and how you equip it.

Good info about paintball supplies here. Sounds like the threads for a paintball tank are just CGA 320 and can be used with a normal regulator...

It works! I picked up a 12oz tank today, the kind that have an on/off and not a pin style valve. As long as you use a nylon washer in the regulator nut it will seal just fine. Now I need to sniff around for a cheap regulator. All this means that a mini setup can be put together for $75, or less if you find deals. I paid $30 for the 12oz tank but I have seen them online for $15+shipping, but I was in a hurry and I wanted a place convenient for returns if it did not work. The whole unit could be made smaller by adding an elbow to the regulator in and using a single guage regulator. Another plus, if you ever decide to upgrade to a larger setup or canister, the regulator still works.

Also, I find this to be good info since it means you could have a small 12oz canister as a backup if you run out of gas.

Just make sure the paintball tank, like regular tanks, stays vertical.

I was not refering to a system, simply the canister. Your right it is not cheaper, really, but for $80 I have a complete system for my 15 gallon and all the parts are useable on my other 5lb system.

Finally got my regulator today and finished setting up the system. Regulator is a single guage economy model from Kegerators, Wine Refrigerators, Water Coolers, Beer Taps, Compact Refrigerators | BeverageFactory.com $29 plus shipping= $36. I had to unscrew the factory output barb/valve, screw on a 1/4"MNPT to 1/8"FNPT adaptor, connect my Clippard valve to that fitting and it was good to go. The new regulators from beverage factory are TapRite and they come with a special fitting the has a neoprene washer inside the regulator nut. These never need replacing and create an excellent seal against the paintball canister. I submerged the whole setup up to the body of the regulator and no leakes.

All total the setup cost me about $80 including the needle valve, CO2 tank, regulator and misc fittings; though I over payed by a few bucks for the canister. They can be found online for $15 plus shipping and I payed $32. The entire setup is 16" tall but you could shave 2" off that by cutting and re-threading the valve stem on the regulator. As you can see in the photo, it is excessively long. Keep in mind though, some regulators, including this one, have left handed threads for this part. Replacements can be ordered pretty cheap though if you need to modify it further.

One last thing you can do with this type of setup. You can purchase an expansion chamber that attaches to the CO2 tank. This would allow you to place the setup on its side without damaging the regulator.

And finally, my poor photo. Notice it is no taller than the Eheim canister filter.

That is sweet- but how do you get it filled?
Any paintball place should be able to refill that canister or you can buy a fill station and fill it yourelf off of your larger Co2 tanks if you have any.

Hey Dennis: I don't see an on off valve on the tank. I thought you had to have this for it to work because the regulator doesn't push in the pin valve on the standard paintball tanks?

New tanks come available with either pin valve or on/off, as shown here. There is a tiny button on the side of the stem that pushes through to turn on the gas, pushing it back stops the gas. On the left side in my photo you can see a little black bump with a red dot. Red dot actually reads, "Push On". The nice thing with that is you don't have the added height from another on/off.

I set one of those up for a friends tank and I really didn't like it. First off the regulator has a very cheap feel to it. Secondly the needle valve and bubble counter are designed to be suction cupped to the outside glass and you need to run tubing from the regulator up to the needle valve and then tubing from the needle valve to the bubble counter. It creates a mess of tubing everywhere instead of simply having all of that connected to the regulator itself. Then you have to plug the diffusor in and it's quite large, way to big for a nano. The system as mentioned from others doesn't even come with a solenoid so you have to purchase that separately, pushing the system to about $200. Finally it comes with a very silly co2 indicator that turns, if I remember correctly blue when the co2 is too low and green when it's good, accompanied by a sad or happy face on the indicator.

I honestly don't know what they were thinking with this product.
