Thank you chewy! The price is just right and it looks like a pitcher of water flowing into my tank. The replacement filters are inexpensive. I am extremely happy with my purchase!

Great idea, They are a little too large to my filter but I could squeeze them into my filter to get them to fit better measuring on my part would help.
I hope that they fit in my large tank.
I am very happy that Chewy carries fish stuff.I always get my cat food there and I save tons of money from the vet that I use to get it from. It cost more to feed my cats than me!
love this item

Definitely does an amazing job for what it's worth. Cheap price too. Definitely recommend changing it monthly as advised, otherwise, the water in the tank becomes filthy very fast.
Just what i needed

These are easy to change and there is no mess. Have had several different cartridges but find this one works the best.
Whisper Filter Media

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.
