🐟 Top Fin Silentstream PF-S Refill for PF10 Power Filters - 12 Count, 1 Year Supply (5.5in x 3.1) - Enhanced SEO Review

Easy to use but buy it with something else or the shipping costs will make it more expensive than just going to the pet store and buying them .

The cartridge is definitely not enough for one month. Maybe 2 weeks if you are lucky. And for the third year in a row, the box looks like it's been run over by a truck.

The product works properly. Your filters should be labeled "PF-S” on the black tab at the top of the filters for proper fitment. The view options are so fancy. What is "clarity" or "thickness" in relation to the quality of aquarium filters?

The food box was almost completely destroyed when it arrived. But none of the filters were damaged. Filters don't last as long as they say. I also need to use sponge filters in the aquarium so the filters last longer. I recommend finding/using another brand.

This filter is excellent for use with Topfin and Tetra filters. I've tried Tetra Whisper Bio Bags and they didn't work as well as these filters. The water was always cloudy, even when I switched to a new cartridge. Also, nothing needs to be removed when replacing the charcoal. I recommend using these cartridges. Easy to clean and very easy to swap out every time.

We've been using our filters like crazy since we started raising guppies for a year-long school project. The filter is unique because it shows us when it needs to be replaced with a little red indicator when it gets dirty. this takes a while if we don't overload the aquarium with too much food at once. Going to the store for them every month was exhausting when we could just buy those 12 packs and cut our trips down significantly.
