Tetra Whisper Power Filter 20, 20-Gallon

I have had a bunch of whisper filters, and I loved every one. I see one guy managed to not be able to comprehend how to get it started...there's always one. Whispers are good filters, one bad review does not a story make, I highly recommend these filters based on twenty years of experience keeping fresh and saltwater reef tanks (but not for reef tanks, they have their own requirements and box filters won't do it) For freshwater tanks, these are excellent filters, ok that's basically it in a nutshell.

This filter keeps my tank crystal clear, and cost me very little compared to a lot of the other filters out there. Quieter than I expected for the price, and the filter cartridges are the easiest to change. Great buy!

When I bought this filter it was working perfectly and was really quite. I took my tank down and put the filter up for two months, when I set my tank back up and hook this filter back up it was extremely loud. I've tried jiggling the intake tube, pulling it up slightly and letting it catch on it's own instead of me forcing the impeller in place, still no luck. I don't know why this happened but the filter started off great. Even with the loud noise it still cleans the tank well.

This is a great little filter for my 10 gallon. I love the fact that you have a control on top even for this small of an filter. I turn it down while i'm feeding and then turn it back up when they're done eating. Nice little filter, the only thing that would make it a 5 star is if they would have put an extension piece for an option like the larger filters. It sits about 4 inches above my gravel in the 10gallon.
