I just bought my first Penguin bio-wheel about 2 weeks ago. I bought a Penguin Bio-wheel 170 for my 55g FW
tank. The other filter is a Whisper 30 that I plan to replace when I use up my remaining filter cartridges that I bought without thinking (again) LOL
However, for the other side of my tank with the Whisper, Ive been sold on the Emperor- the new redesigned one. Consider it done (well at least when my Whisper filter cartridges are depleted which might take a while!)
The bio-wheel I bought two weeks ago seems to be working great, and my water is clearer than usual so I credit it to the penguin. Ive never had a bio-wheel and its kinda neat to see it move (slow and choppy now) and hear the water sound. Doesnt bug me... I have a canopy on the top of my tank and it deadens some sound it seems.
