The filter on a scale of 1 to 10. I would give it a 6.5. 7.0 at best. I think it is still light years behind the Eheim Classic Series and that filter has been around 20 + years. It lags behind in quality and performance.
I've had mine on my 125 for about 4 months. It works great and i think its quiet especialy compared to a HOB. I do get the bubbles everyone else is talking about, but its after working on it and they go away in a day or two. I would recomend it.
