I was thinking it would better just to have both bottles connected to a t-piece then the line into the bubble counter if that makes sense.
I do not use a t-connector. Both CO2 lines from the generating bottles run directly into my bubble counter bottle. In other words, there are 3 holes in the cap of my bubble counter: 2 flowing in from the generator bottles and 1 flowing out to the tank. I even use a different color of airline tubing for each generator bottle. This makes it easy to count the bubbles coming from each bottle separately. Also, don't forget to use check somewhere along the way.
