This works out well, even with a 4 LPM air pump. It puts out more air with the small pump than the cylinder air stones, but appears to put out less with higher powered pumps (roughly 15LPM for each air stone, the cylinders put out more bubbles).
The main other advantage is this doesn't roll around like the cylinders.
So if you have a low air flow air pump (4LPM), or you have a bigger area, where you want the air stone to stay in the middle, this is better. If you have a higher air flow air pump (>15LPM), and don't care if the air stone moves, the cylinder shaped air stones are cheaper and work better.
