The pump was easy to install, it works just like it should, and it was delivered rapidly. The price was not out of line compared to other options, but everything is overpriced these days.

Tetra Whisper Internal Filter for Aquariums 20 to

I'm using this in my makeshift outdoor "pond". I have my carnivorous plants on a platform, just barely in the water, and I have a small shield to slow down the flow between the two. It is very functional. I will have to find better looking pots to make it more glamorous.

works very well!

I ordered this filter for a 10 gallon tank. I do not have fish in it yet, but I do have a few live plants. My tank also has sand substrate with waterlogged wood pieces. My old filter crapped out on me finally so I decided on this one to replace it as it was a fair price. I was AMAZED at how quickly it cleared up my tank. it had a thick layer of sediment on the bottom and this filter cleaned it right up, I was shocked! It's also whisper quiet, I can't even tell if it's on, sometimes I have to double check to make sure it's still running. lol Highly recommended!
