After reading a lot of your guys reviews and opinions I decided to upgrade my Tetra Whisper 20-40 to a AquaClear 50. Man what a difference between night and day. First thing I notice is the AquaClear requires less wall space. Its roughly ½ free space from the wall now. Then there is the lip portion, it doesn’t hang so far into the tank its really nice. I think the lip portion saved another ½ space also. The noise difference. Tetra Whisper is a miss leading name. Compared to the AquaClear it should be called Tetra Screamer. Biological value? You all probably know it but the aqua clear just has a lot of media going on, the surface area alone is greater when you factor in every thing inside it. End result is I am incredibly happy with the purchase.
