Top Fin Silenstream PF-S Small Filter Cartridges (6 Count) Refill for PF10 Power Filters (5.5in x 3.1in)

Do not buy this. The same product is just $13 at Petco.

Works great for my fish tank!

perfect filters for small tank

Fits and gets the job done.

They go in a fish tank!

This is the correct filter refill for my tank. It fits. It works. Price is a little higher than buying from a chain pet store.

Prepared aquarium, 1 week later fish arrived live. Very pretty fish. However, they all died within 30+ minutes.Didnt take pictures as recommend, felt I didnt need to. Guess I should have, but felt this would be a safe fish transfer into my aquarium. Guess Im not getting a refund.....her disappointed.
