I found that my bubble rate would fluctuate when I used too low of a setting on the adjustable pressure regulator. When I went from under 20 psi to a full 30psi, the bubble rate remained far more constant after being set.
(I'm using a beverage factory dual gauge regulator and a Clippard needle valve, btw.)
And to echo what James and Rex have said - I was disappointed to see very little pearling when I switched to HP CO2. Only when I started dosing Stump Remover (KNO3) and Fleet Enema (PO4) twice a week did I see major pearling and weedlike growth.
