Rated 1 out of 5 by Rocfish Poor design
My ex30 looked great when I first purchased it. After the first cleaning the frame work failed to hold the filter . Then I discovered replacement filters are twice as much as standard filters . After 3 months I had a power outage and the pump failed to restart . There is no way to access the Impaler to get running again . I'm done with tetra .

Rated 5 out of 5 by JayWal effective - and so quiet!
I barely know the filter is on; it lives up to its name. I've actually checked to see if it was on at times because it's that noiseless. I've had tanks for years, and this is by far the least noisy filter I've ever had. And the tank is crystal clear.

It is quiet AND very effective in cleaning/clearing the water of my fish tank.
