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

FISH ARE HAPPY. CLEAN TANK.

Muy buena calidad excelente para mi pecera

Easy to use and came as described

Our Petsmart store closed so I was happy to find this as its the only kind my filter will use. I love these as they are long lasting even in multi fish setups.

It feels good. I change it every three weeks and you can see that the filter is very dirty.

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.

Cheap and fits perfectly.

I don’t know if I got defective filters but they’re only lasting 2 weeks before my tank is saying that they need to be changed. Our previous filters would last a full 4 weeks.

They are ok

Love these filters. I use them when needed in my five gallon fish tank.
