Anytime I have erratic bubble rate, it’s always a leak - slow leaks are not simple to detect, and some may only be apparent when system is under pressure, eg, diffuser blocking, solenoid closed, solenoid not opening fully
(Which is why I’d prefer the retailer to test the system ... but this is much more in CO2Art style)
