Tetra® Whisper EX45 Filter System
Great filter and customer service
The first EX70 large filter I bought was quite loud. However, I really liked the simple design and set-up, and the ease of cleaning. So, instead of switching to another brand, I called Tetra and they said they would ship me a new filter, directly to my home, no charge whatsoever. Moreover, I was only on the phone for five minutes--no bouncing around between departments, having to repeat my story, or waiting on hold. The new filter arrived and worked quietly, as suggested by the name, "Whisper." I've had it running for over five years now and it is as quiet and efficient as ever. I cut some foam to fit the media wracks, not fussing with chemical or mechanical filtration. And the blue and white scrubbers are an added bonus. The water in the tank is crystal clear. I also like the slim profile of the filter, which allows the tank to be relatively close to the wall.

Works Well, GREAT Customer Service
The filter works well. Most filters are pretty much the same, but I like the extra insert (the blue thing) that allows beneficial bacteria to grow. What I liked most was the customer service. My filter was missing a piece, so I called to see if I could buy a replacement. Instead, I was on the phone for less than 5 minutes, and they sent me a replacement for free. It came very quickly! I was very impressed, and have never had such a positive customer service experience. Other companies should strive to this level of service.

Works well, but louder than expected
I bought the Whisper EX 70 for my 55 gallon freshwater tank. It was very easy to set up, though I'm surprised that the impeller is in the tube, and a little dismayed that the cord gets so close to the water - the engineering doesn't seem well thought out. It's also quite a bit louder, mechanically, than my old MarineLand filter. The indicator strips are a farce - I've had the filter in place for about 2 weeks and it's already telling me to change the cartridge, which is unreasonable considering the cost of the odd-shaped replacement cartridges. But, the water in the tank is very clear. I like the special insert for facilitating healthy bacterial growth. The large filter and long tube ensure that the water circulates well through my tank. All in all, I give this a "good" rating, but it's not a perfect product.

This product had cheap features
The part of the filtration system that sticks into the tank water that sucks the contents into the filter keeps falling off after 6 months of purchase of the product. I now have to keep reaching into the tank at least 2x a day to place the piece back onto the base of the filter.
