bump this for one its a great thread more people should read it so they arent so intimidated by pressurized co2. and because id like to know if anyone has had any experience with Aquatek-California? and their ""all in one" regulator setup that includes a "cool to touch" solenoid, needle valve, and a duel gauge regulator? if its quality pieces id guess the end result would be quality also. idk ill probably start my co2 setup sometime next week and i just want some feedback about the company! thanks again guys!
