This works by having the water enter at the top on the side (note that the water will swirl, due to the location of the inlet), the CO2 in the middle of the top, and the water leaves at the bottom. The bioballs are supposed to trap CO2 bubbles to keep them inside longer. I made my own several years ago, almost like this, and it didn't work well. The standard PVC pipe external reactor works a lot better and costs very little when you DIY it.

i have one and have to agree with others that it is not very good at dissolving co2. the powerhead i attached to it became co2 locked after only a few hours; guess i used a too high bubble count. i can't imagine using this on a tank larger than 10gal.

i should mention that i used tom barr's venturi loop mod on mine. that probably contributed to the co2 lock.
