I have this tank, regulator, solenoid and needle valve. Can I just add a low pressure gauge to this or should I build a whole new regulator?

Did you forget to add a picture?

A low pressure gauge, while not absolutely necessary, is definitely a major help when trying to dial in CO2.

I see the picture...

This type of regulator is not for aquarium.

Technically correct..
Looks to be a set outlet pressure of 50psi. soo IF one can design a system capable of handling 50psi
and replace/add a decent metering valve it "could" function as a CO2 reg for an aquarium.


Certainly wouldn't be my choice though.

Silly marketing lists the "type" as usable..

To echo Bettatail and jeffkrol, I would advise against using this for an aquarium, as is.

I've only seen these being used in growth chambers to increase atmospheric co2 for climate change studies.
