I bought this filter and thought it would work great in my fish tank. Well, I think it worked very well, but the whisper did not work. The Impeller was so noisy that I had to close my bedroom door at night so that I could sleep. I know that all of the filters will produce noise, but this product promised to whisper.
After a few days, I went to PETCO and bought a Whisper immersible pump and trashed the EX 20.
