Tetra - Whisper EX70 Power Filter 45-70gal

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.

I love this self priming and really great I use these on all my tanks .. :D

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!

These filters are junk.changed my tanks and they would not start up.I through away three filters and extra cartrigdes.my cascade power filters at least start every time I change water.
