Best HOB Power Filter

I have an emperor 400 and so far I am very pleased. It's around $45.00 if you go on-line @ PetSmart and bring the printed price to their store. Saves somewhere aroun 20-25.00
 
I personally use Whisper on some tanks, even though it does not have the reputation of Marineland or Aquaclear, but as long as you keep up with your routine water changes, most HOB's are good for keeping water healthy. I'd choose a Marineland HOB over some others mainly due to the biowheel, but I'd go with anything exceptthe Penn-Plax Cascade.
