Well I finally have my pressurized system.
Now I need a few questions answered.
This is what I have....
5 lb tank
two gauge regulator with needle valve
Aqua Medic 500 reactor(disfuser)

Question 1
one gauge tell if the tank is full/empty the other is the pressure coming out of the tank...what should that one be set at? It goes from 0 to 160.

Question 2
I can see the co2 inside the Aqua Medic 500...swirling around...should I see it coming out somewhere?
