Tetra 26218 Medium 5-15 Carbon Filter Cartridges (2 Boxes of 3-Filters)

Easy to use and fish are doing great

The listing is exactly what arrived.

company is a cheat

These filter keeps my tank so much cleaner then the brand I got at walmart. Thought they were the same but to my surprise I have not had to clean my turtle tank in over a month and it is still very clear. With the other brand I was cleaning the tank every 3 weeks.

Happy with product but compared to some other brands, is quite expensive. Wish there were some generic alternatives

Great for my fishes

Easy to use. Pull the dirty one out, pop in the new one in. That simple!

Excellent way to purchase

Purchased online and price was a better value than buying in a store.

Good.
