Have just fitted an up aqua inline diffuser, however I'm yet to see any bubbles appearing ... the bubble counter slowed right down and i had to turn up the flow from the CO2 tank to get them going again, but, as I said, I couldn't see any micro bubbles. Then I looked at the pressure gauge and it's reading 1.5 bar. How do I adjust the regulator up to 1.7-2.0 bar ?
Thanks
Richard
