Great Water Filter = Happy Fish

Tetra Whisper Internal Filter 10 to 20 Gallons, with Air Pump is a great yet inexpensive option for cleaning water in Fish Tank and giving fish plenty of oxygen to live and be happy. I have purchased before and would do so again.

Love it.. My last one took a crap. But I never noticed how loud it was until I purchased this new one and it's so quite.

Works for about a year in a ten gallon aquarium with 2 fish and constant cleaning of the gravel and changing out the expensive pads monthly. zero noise level. I see bubbles coming out in the water for the first couple of weeks and then nothing.
