My plants perform much better without them. By not using airstones, you will get more of a "flooming" effect, which give's your plants maximum amounts of oxygen 100% of the time.
Curious - How do you oxygenate your root zone without air stones??? Drip feed re-circ???

What's your method that "gives your plants maximum amounts of oxygen 100% of the time"???
