Great Filters


I have 2 of these on my 210 gallon aquarium.
<br>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.

Love these


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

Excellent Design Improvements


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.
<br>These filters are silent, dependable, and cheap.
<br>The only con I can note is that this filter no longer has a flow-rate modifier. I hate that.
<br>Otherwise, good job, Whisper people!
