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

Work great for my aquarium

Works well. Lasts 1 month in my 20 gal. tank with 3 medium size fish. Im impressed.

Perfect for the price and easy to use for my 10 year old.

always good quality

Box was busted but filters still fit. Arrived on time.

Good price for large amount. Shipping was very fast.

This is a great filter to use with both topfin and tetra filter machines. I tried the Tetra Whisper Bio Bags Cartridges and it did not work as well as these filters do. The water was always cloudy, even when I replaced with a new cartridge. Plus there is no mess to clean up when changing out the charcoal. I recommend using these cartridges. Easy to clean and very easy to replace each time.

Good

Soon as I used this filter verses petsmart because I was trying to save money with this being a better deal … water turned white. And my betta wasn’t like himself very lethargic and hung out at bottom. I did a water change and used another filter thinking maybe it was something else and within 2 days of water change/new filter white murky water again and my fish would not come to the top to eat. I have an established tank. There is no reason for murky water when I put correct amounts of bacteria starter/conditioner. These filters killed my poor fish. I do not know what’s in the actual filter but please beware.

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?
