Best internal filtration system I've used. Filter bags come assembled. Don't have to take the time to put anything together and add the carbon medium. The carbon is only effective for two weeks, so I switch out the filters twice monthly when I do my water changes. The tanks run well with this filtration system. Chewy prices have always been very good, so I'll continue to use this company for all my pet needs. Thanks Chewy! B Bradbury

Filters for tank

I love all chewy products. These, I was able to use 1 before my dogs ate the rest. And Im thinking they approved mightily. I should say I did notice a reduction

Works Great

I have been using these filters for many years as I have iridescent sharks that are 25 years old. I prefer these filters to the ones you put together yourself.

Amazing Savings

While these filters have always performed well in our fish tank, the cost savings of 60% over my pet store was truly amazing and appreciated!

CHEAP BUT EFFECTIVE

I love how cheap but effective this product is a few months back it would clog so easily, but I got the 30-60 dual tetra filter and change one of them each month

I love how cheap but effective this product is a few months back it would clog so easily, but I got the 30-60 dual tetra filter and change one of them each month and so on. People complain about how it clogs, but simply aren't doing enough maintenance on their tank. You must do frequent water changes, treat the water to break down waste and more and it'll work perfectly.
