Top Fin EF-S Element Filter Cartridge Value Pack 12 Month Supply 2.1 in X 3.7 in

GREAT even though its just a fish filter

I purchased these filters for my sons beta fish tank which is made from the same brand top fin. First off all these filters seem to be hard to come by. I cannot find them in local pet stores at all. Thats how I ended up here. I changed the water replaced filters and on the 4th day the water was nasty starting to get cloudy. By day 7 water was green. I decided to clean and treat throw those filters out and use 2 more filters keep in mind I purchased 12pk of filters so that is 4 used in a two week period. I am currently in the process of using another 2 because they are not working. Pet store recommended changing tanks and brands because they have been hearing negative feedback also. Will not purchase again.

My little fish love fresh filtered water again

Very easy to install

Work as expected, better value than the 3 packs at local big box pet store.

Great value

Used in my 3 gallon tank.

Perfect fit for the aquarium

Great

My package came slightly damaged and squished in the bag. The box is damaged and the item inside is fine.
