I've been using these in my aquariums for many years and have never been disappointed. They do an excellent job of keeping the water clean.

These filters are the original!
They work perfectly.
I love the way they clean up a 55 gal. tank in no time.
Thank You Chewy
El filtro insertos were correcto.

Usually buy these in local pet store.
Even with delivery charge, much better price with Chewy.
Correct Product but shipping box was damaged and sent to wrong address

A lady called my sister to state that she was legally blind and accidently opened my mail. It was delivered to 1505 instead of 1606...when I picked it up, the box had damaged to one side - as if it had something heavy drop on that end. The product that I ordered was a very light product and thankfully not breakable. The product was in perfect condition even though the box was damaged and it was sent to the wrong address. Which of course is more the delivery company's fault and not chewy.com's issue.

Great filters. Chewy offered the best price for these filters and they were very quick in shipping them. Will never get our filters anywhere else.
Does its job.

I have used these filters as long as I have been using the 350 Magnum and have no problems. I found that I can rinse them thoroughly and use them at least 2 times and I have a 100 gallon tank.

does as it should and is better than any other filter I think on the market
