Those are safe to use and actually quite common. Only thing I don't like about that set up is no solenoid.

I don't know where you might be on your planning and experience but there is a small point that you might want to do a bit different if you do get into doing the same. It may be mentioned in the 100 pages but I did not read them all?
The small tubing goes on the cutoff valves using a compression fitting. The one in the third picture? Normally one would not want to use tape on this type fitting. The compression of the ferrule against the fitting is what makes the seal.
Not a big thing and it seems to work for him but it isn't needed and there are times when bits of tape break off to go to some point where they clog things up.

I have two setups almost indentical to those. My opinion is to get a good on/off valve. Also be sure the needle valve is rated to handle the pressure from the paintball tank. Home depot had some that are only rated for 100psi. I made the mistake of buying one of those, and ended up gassing my fish one night.

Bump: Heres a pic of mine with a better on/off valve, and attached brass bubble counter. Works great, and no issues in the 1 year I have had it running.
On/off valve was $30, needle valve and brass elbow $10, jbl brass bubble counter $20, and teflon tape $1.

I had the same question about it. It doesn't have a pressure regulator. Thus I wouldn't try. Some like Hoppy feel it is not save.

What is the item before the brass bubble counter?

Needle valve. Allows you to fine tune the amount of co2 that goes out.

+1 on getting a good on/off valve. I would spend at least $30 on a reliable brand.
Heres mine!
I wouldn't recommend my on/off valve since I really don't like the design and I had to add an o-ring to it myself.
I invested on a better needle valve but the one in the link works great too.

I think it would depend on how often you have it on and how big of a tank you are going to get. I have a 24oz which I think is the biggest paintball tank available. I keep it on 24/7 at a 1 bps with my inline diffuser. One tank usually lasts for about a month for me. I keep two tanks handy since the closest place that refills paintball tanks is a hour drive away.

It is not the same as a pressure regulator.

Its considered a needle valve. Im my setup, the top yellow knob opens up the paintball tank,and releases the co2 from the paintball tank. The needle valve allows you to adjust how much of that pressure is going out. Some people use needle valves and some dont. In my opinion its much smarter, and safer to use a needle valve.

Im running my setup on a 20long. Co2 is on for 7hours, and last about 3 months @ 2bps.

Only one month @ 1 bps? That is considerably shorter than the durations listed in the OP of that other thread. Im trying to get an idea how long a 24 oz will last is why Im asking. Obviously depends on how long you run it every day, but that seems like a pretty big difference.

Quote:
At 1bps on a 24 oz PB tank. You can get 5-6 months.
At 2bps on a 24 oz PB tank. You can get 4-5 months.
At 3bps on a 24 oz PB tank. You can get 2-3 months.
At 4-5 bps on a 24 oz PB tank, You can get 1.5-2 months
At 6-8 bps on a 24 oz PB tank, You're looking at 1 month before refill.

Maybe some people have unknown leaks that are causing shorter life span. If your considering cost, its definetly much more cheaper then diy. You should start a poll
