This is interesting, because I just installed a JBJ set, too. I noticed something similar with mine, except that water repeatedly backwashed into the tubing unless I held the tubing straight down in the water. I had to turn the intake tube on my Magnum (the tubing is threaded into it) at an angle to keep the water from backwashing as much. Still, the pH reading said that the CO2 was getting into the tank.

Bah, I don't know. Like I said, I removed the BC anyway. If anyone comes up with a solution to this problem I would love to hear it.

Bah, humbug, Bob Cratchet. I want an exact accounting of the CO2 loss in this bubble counter. I think a foreclosure from First National Bank of CO2 is in order. Do them good.

These stories get stranger and stranger. I inject my CO2 into the inlet strainer of a Magnum 350 and I have had no problem whatsoever with any kind of "backwash" , or anything remotely close. The CO2 goes into the bubble counter, it goes out, it goes down the line into the inlet strainer, and I can see it bubbling into the inlet through the slits in the strainer. The bubble rate in the BC is slightly higher than at the strainer. Say 1.2 bubbles/sec. at the BC gives 1 bubble/sec at the strainer. I attribute that to difference in bubble sizes. There is something strange here. Bah!

"the First National Bank of CO2" - too funny!

It was odd-looking (and never happened with my yeast generator), seeing the water trickle back into the tubing - almost like a battle between the gas and the water. I could take off the bubble counter, but I kinda like the security of being able to check it now and then to see if the output looks to be holding steady. Which it does. (Back to the yeast generator - that didn't backwash, it just repeatedly leaked! 'nuff's 'nuff.)
