I find airstones to really suck... very limited in terms of air availability, especially in a large tank or over stock with fish..
Instead, i like the air wand... I will say that I mostly rely on Ac110's waterfall effect to generate a well circulated tank.. I will try the Air disc next.. that something i always wanted to give a try....
I've always had issues with airpumps breaking down on me after a few months.. Even stuff like Hagen, But I find Elite to be some what better.. but eventually all airpumps will break down, because the rubber part of the air generation gets worn out over time....
