Top Fin Silenstream PF-S Refill for PF10 Power Filters 5.5in x 3.1- (12 Count) 1 Year Supply

I will buy these again for our ten gallon fish tank

this product that is supposed to be changed out monthly only lasts 2 days in my cleaned ten gallon tank, the indicator on my filter turns red to tell me to change it after one day.

I needed replacement filter cartridges and ordered a year supply. These were a great value and easy to install plus they came super fast. I have a 10 gallon top fin tank.

The price for these 12 was approx. what I paid for 2 at my local pet store.

fit perfectly

Cheaper then department store. Love it.

Product works as expected. Your filters should say PF-S on the black tab at the top of the filters for these to fit correctly. The review options are so bizarre. What is sheerness or thickness in reference to regarding the quality of aquarium filters?

always good quality

Good price for large amount. Shipping was very fast.

A cartridge definitely doesnt last a month. Maybe 2 weeks, if youre lucky. And for the third straight time, the box looks like it got run over by a truck.
