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

Cheap and fits perfectly.

The filter and media are self-contained. It fits and works as expected. The change rate is as to be expected as well.

100% will buy these filters again !

This is double the price at Petsmart and is price gouging . The filter itself works fine

Worked great and fit right into my filter

Needed these last minute. They arrived fast and were perfect . price was better than the store .. Atleast for me . I Will probably reorder from here :)

Fits and gets the job done.

I’ve used Top Fin filters for over a decade for my goldfish aquariums, but it seems like in recent years the quality of the filter cartridges has really tanked. According to the box, one filter cartridge should last you a month, but I’m lucky if it doesn’t need changed in a week or less. I’ve even tried pulling them out when they are needing changed and rinsing out all the gunk with conditioned water, but even that only buys me an extra day or so of use. This goes without saying I feed my fish only enough that they need 2 times an day, and change 20-30% of the water via gravel siphon weekly, so there shouldn’t be so little use out of these. No fault of the seller, but I wish Top Fin filter cartridges were better quality like they used to be.

Our fish tank is extra clean. We love these filters!

Very good
