This is much better than the traditional air stone. The disk lays flat on the bottom, and you can cover up most of it with gravel so its basically invisible. I use a Great Choice Air Pump 20 with it, and it creates a very nice round column of bubbles and increases the flow in the tank quite a bit. I highly recommend this over regular air stones.

It's my first airstone and I love it. It does not float and the bubbles it makes are perfect.
