Home Depot has this
Viagrow .5 to 15 SCF CO2 Regulator for $89.97 with 3 year warranty. Will it work for aquarium co2 systems? Can some one hepl me to use this reg. I have limited Co2 knowledge.
Thanks

Those regulators are more meant for hydroponic systems (you can see the flow valve). You may have difficulty in adjusting the working pressure down to the levels we require.

Furthermore, you will need to purchase a needle valve to further refine the flow.
