For a bubble tower (or any bubble trap for that matter) to be effective, the downward flow rate of the water must be slower than the rise rate of the smallest bubble you are trying to filter.

The bubble tower effectively takes the fast moving water coming down the overflow drain (let's say 1" pipe) and in theory slows the flow rate by expanding the diameter of the pipe (say 4"). Here's a sketchup of my bubble tower.



The problem is the 1" inlet pipe to the tower is centered and aimed straight down. When the water exits the 1" pipe, you want it to widen out it's flow pattern so that the water moves slowly down to the bottom of the tower. In reality what happens is the 1" water inlet pipe creates a high velocity jet that shoots straight to the bottom of the tower carrying bubbles with it. The water break is some obstruction that you place near the inlet inside the tower to break up and distribute this jet.
