Between an AquaClear, Marineland and possibly a Tetra Whisper, which HOB
filter would be the best pick? I'm still debating getting rid of my two Aqueon QuietFlows because I just cannot seem to establish clear water in my 60-gallon, and I'm beginning to get fed up with these filters' operation -- I mean, I'm running TWO filters in my tank, and the water still isn't clear (unless my fluorescent lights are creating the smoky, whispy look in the water below...).
The Marineland PRO line seems interesting (what is it...an Emperor or Penguin?) because it has dual waterfalls, but I keep hearing about the AquaClears. Is there one that is going to yield cleaner/clearer water over the other? What would be recommended for a 60-gallon with fancy goldfish that need a lot of filtration?
