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

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.

FISH ARE HAPPY. CLEAN TANK.

A great filter.

fits well in my silent stream filter

Just as described, these last about 3 to 4 weeks for me.

As described. Shipped fast

4 stars because filters where shipped in a bag and the box of filters got squished. Should have been packaged in a box. Thank goodness item was not damaged. Other than that ordering was easy and item was delivered in a timely manner.

Great value and easy to use

great filter for your aquarium!

they work perfectly easy to change my tank looks great
