Can anyone suggest a almost completely silent filter for a 20 gallon tank? I was going to go with the Tetra Whisper 40i but it's HUGE. I need a smaller internal filter or a very quiet external filter that can filter the water the same, or better than the tetra. Also trying to find as inexpensive as possible with both the filter and replacement cartridges (I know most of the time you get what you pay for).
