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.

Rated 3 out of 5 by Fishie1x2 Impeller issues after 1-2yrs
I have had 2 of these filters in the last 5yrs. I have have to replace the rubber ring on the upper hose above the motor and then after 1-2yrs the impeller started to make a loud noise. I love these filters when they are quiet. Keep the Aquaruim clean and you need to be careful when cleaning the impeller. If you want an awesome filter that last 2yrs until you need to replace the impeller then no guarantee it will continue to be quiet. Really bummed and wrote to them in regards to this issue. Hopefully they will get this resolved quickly.
