I currently own all 3 and the ac500 is the best the 350 is noisy and the biowheels get hung up easy.
The 400 is a good filter but it is a black bastered i can't see the bio wheel turn
it pisses me off.Get a ac 500 and chilerellno has got a tutorial on how to ad a bio wheel to it that makes it the the best hob ever
.lol
