Shay,
I hooked two Hagen bottles to a single ladder (using a T) and found that the larger bubble (created by combining the bottles) dissolved only to the point that a bubble from a single bottle would have. In other words, the CO2 from the second bottle is essentially wasted as that's the size of the bubble that exits the top of the ladder.
I now have the two Hagen bottles connected (again with a T) directly to the intake of a Magnum 350 filter and never see any bubbles exiting the filter's outlet tube. I probably should move to a 2 liter bottle but I hate wasting stuff I already bought (the Hagen bottles).
Bill
