The Emporers are the 400 and 280 twin pump filters with the spray bar driven bio-wheels. The 350 is a penguin...but yes they make them from the penguin 350 and even for the wispers...in fact they turn the wispers and top fins into an acceptable HOB filter.
Hmm I think I smell an upgrade to an emperor 400, anyone want a almost brand new 350 penguin lol? I'm going to have to get 3 of those pads for my whisper, and 350, that is if no one wants to buy it lol....
