Bought several packs of these stones. There are so many differences in airflow, one bubbles like crazy and the other three "channels" of the manifold have almost no bubbles. It took weeks of fumbling, swapping out stones and placing the valves to even out the bubbles. Too much effort for something that oxygenates the water and keeps it moving.
