I just bought one of these of craigslist for 15 bucks except the co2 bottle expired a month ago with a full tank of co2 in it, still a damn sick deal though.

Is it recommended to turn this thing off manually at night?
I leave it on 24/7. Needle valve is adjusted to 2bps. Been running like this for almost close to a year, no problems with tank or algae.

If I wanted to, I can always turn it off at night and turn it back on in the morning when my lights switches on. It's fairly easy to adjust, you'll be surprised.

Thinking of mounting the paintball tank horizontal on the wall. I wonder how it will put to much pressure on the needle of the tank? Any thoughts anybody?

CO2 cylinders should not be mounted horizontally, unless you want liquid CO2 to come out...

I had a feeling it was a bad idea. Thanks!!

Bump:
would this be possible with a 15g tank?
Yes!! Found a thread with 1 using it in 15g tank. Post #1 here tells you how long it will last. Another version of paintball tank Co2 system here.

I had a question about the Needle valve. I can't find the ones from Lowes or Homedepot described in the guide. Would this one from amazon work?

Watts LFA41 Compression Angle Needle Valve, 1/4-Inch C x 1/8-Inch MIP - Flush Valves - Amazon.com

If not does anyone have any other suggestions?
It's been pretty well established in this thread and in many others that this type of setup is an all-around pretty bad, dangerous idea. But yes, if you follow the instructions originally spelled out in this thread, your link is the type of valve that is talked about.

But, seriously, don't do it.

Ok thanks! I didn't have time to read through the whole thread so thanks for the update!

Is there any other DIY C02 guides that you know of that work and are safe?

Thank you again!

Hello,

Thanks Jaggedfury for these detailed setup instructions. I have followed these and have a 20oz setup running on a 24G Tank. The only problem I am going through is I cant set a stable flow of CO2 from it. I have bubble counter and but not using gauge. When adjusting Needle valve I am unable to get stable flow. Bubbles when setup to 2bps keep going slower and slower and after few hours I see less than 1bps.

Any help greatly appreciated. Thanks in advance.

Regards,
Ron

Any interest in saving me some time and giving me a TL;DR version on why it's not a good idea??

Thanks

Hi, i recently set something very similar to this up. I've been having issues getting my co2 to a decent level with the needle valve. I only require about 1bubble/sec, but in order to achieve that the needle valve needs to be pretty much all the way closed and over time the co2 stops flowing almost completely. If i open it up a little more, too much co2 flows. Has anyone else experienced this/have any tips? I was thinking about upgrading to a regulator w/ solenoid but that would effectively double the cost of the whole setup, where the whole reason i went this direction was for lower cost.

OK, after going through all 161 pages of this post it has been extremely informative and although I am doing as much of this build DIY as I can, at first I will go with the pre-fabed regulator and valves. Once everything is built and established I will come back to this and experiment. Thank you to all on this thread!
