Question Paintball DIY Co2 without presure regulator safe

I have been reading Paintball DIY Co2 system without a pressure. Logically doesn't seem safe without a pressure regulator.

Has anyone has had a problems using Paintball DIY Co2 system without a pressure regulator?

I am not sure how you would use a CO2 cylinder without a pressure regulator, at least for our purposes.

For things like paintball guns, which need high pressure to propel the paintballs, it might be fine.

However, when we are injecting CO2 into our aquariums, we require much lower pressures, and without a regulator (and a needle valve) to control the flow, there is no way to control it.

If you take the time to go through that (very) long thread, you will note that there are several disadvantages to such a system.

The biggest one is the lack of reliability and lack of fine control that the system affords. While it is definitely cheap, a slight bump of the valve (that is not suited for the fine control that we require) will send your CO2 injection rates skyrocketing, leading to potential disaster if not caught in time.

Using a DIY with ASA valve and Watts needle valve from home depot. Safe? - hook it, test it, use it. I would say it's safe. You definitely do not get the end of the tank syndrome.

The downside: really hard to control the output, as the valve needs to work at full pressure. I would not use it in combination with a glass diffuser, as turning a little bit the valve can release a really high pressure into the tubing and either blow the tube or the diffuser. I have an inline diffuser, and the extra CO2 (if any) when trying to adjust the valve just goes in the diffuser tube and gets dissolved into the water flow eventually. Cheap, easy DIY, not reliable.
