Top FinEF-S Element Filter Cartridges (6 Count) for Fish Tank

Needed 2 filters for our 5 gallon split aquarium with beta fish. These were the perfect fit! Be sure to rinse well. Between the live plants and these filters, our test strips are indicating perfect chemical balance for over a month!!

I use these filters for my aquarium and often they are not available at the pet store. So, I am happy to be able to purchase them from Amazon and very convenient.

Have to replace offten.

Filter fit the tank fine and maintained the water cleanliness. Made from basic materials and the filter frame is 100% plastic. Water flows easily though the filter material. Overall no issues with this item.

Box was smashed but contents were not damaged

I purchased these for my 5gal tank and it's perfect for the water change.

What about these filter is affordable for the number of filters that comes in a pack.

Please put my little tight perfect. Exactly what I needed.

Great for small fish tanks

This works great. Bought a similar product made by another company by accident but will go back to TopFin in the future. They are better made filters and fit better in the machine.

Good product

Exactly what I wanted and needed

They don't keep my tank clean and I am having to change the water every two weeks
