Fishy Filters

These filters have always been great. The last batch was defective, activated charcoal spilled everywhere, but usually this is a great no fuss product. Chewy makes saving and reordering pet supplies a breeze.

Tetra Whisper Bio Bags

These filters are perfect size. They were half the price at other big box stores. Delivery was only 2 days. Always use Chewy for all my supplies.

Best Filter

The filter for the quiet tank filter fits perfect and is easy to use. There’s no problem putting it in and when it’s time to change all you have to do is pull it out and replace with another. It can’t get much easier than that!!

Filters work as good as the other brands

These filters work great! At first I was skeptical because they are much more economical than other brands but they turned out to be just as good.

Cloudy water

It seems my fishes water clouds up much quicker since getting these and using them. In less than a month; we’re on our 3rd one

Eazy to use

So convenient to use. What can I say? Take the dirty filter out and put a clean new filter in! It's just that eazy. I do this once a month. And I have very happy fish and a clean clear fish tank.
