The world famous Whisper power filter updated for the 21st century. The Whisper EX70 aquarium power filter offers a host of modern conveniences and advanced filtration capabilities to keep your aquarium clean, clear and healthy. Extra-quiet, in-tank motor design promotes even quieter Whisper operation, eliminates priming and lowers the filter's profile. Rounded filter chamber design promotes circulation and reduces sediment build-up. Enhanced biological grid promotes optimum bacteria growth. Squeeze-to-open filter cartridge design keeps your hands clean when performing regular cartridge changes. Whisper EX70 is designed to filter aquariums up to 70 gallons with a flow rate of 340 gph. Requires 2 large size Whisper Filter Cartridges.

Whoever made the improvements to the Whisper filter is a genius. One of the main things I love about this hang-on-back filter is the different bio screen design. In the older models, the biological filtration was supported by a sponge that sat in back of the main filter cartridge. Now the biological filtration is a screen with little spikes on it. Someone must have looked at the bio ball design that many sumpump filter systems use (wet/dry) and applied that surface concept to this filter. Smart! Instead of worrying about the sponge's getting clogged, one can simply take out the filter screen and smack it a bit against the bottom of the sink. This clears the material that might catch onto it without damaging the wonderful little nitrifying citters who keep our tanks poo-and-pee-free.
These filters are silent, dependable, and cheap.
The only con I can note is that this filter no longer has a flow-rate modifier. I hate that.
Otherwise, good job, Whisper people!

Great Filters 2/21/2014
I have 2 of these on my 210 gallon aquarium.
Instead of using these as mechanical filters, these work great to grow plants out of the filter. Best plants I have found are peace lilies.
