I haven't experienced that and haven't heard of it. Is it possible the
connection was overtightened? Also, have you tried keeping the bubble
counter less full of water to keep the water from being sucked out?
From what I understand, you only need enough water to actually count
bubbles (in which case, once you have your desired flow, would any
water be needed at all?)

The amount of water doesn't matter, the PowerHead (RUGF) will suck the
bubble counter dry in no time. The direct exposure to the CO2 seems to cause
the plastic to crack. It's also done a number on the rubber seals. I taped
the cracks on the Bubble Counter as a temporary measure and a few hours
later the cracks were double their original size.

Since I have a PH meter, I've just plugged the tubing directly to the check
valve coming off the regulator.
