Best Filter for 55 gal???

[fishieperson321]

I prefer Penguins all the way. They are compact wet/dry filters that keep the tanks free of ammonia and are quiet. My local fish store uses them on all of their tanks except for 2 and they use Whisper and Aqua Clear. They even let me take it apart and check the durability of the parts when I went to buy a new one. They said for me to take my time and they will tell you that they are the absoloute best!!
