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

Bought these instead of more expensive ones. They’re great!

the fact i have 2 packs of filters make so easy not to have keep watching how many you have left before having to shop again love the twin pack smart move.

Works as advertised

The listing is exactly what arrived.

Perfect fit

Excellent way to purchase

Great

These are the bio bags which are different from the product number and description on this listing. Returning now.

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.

Received this item today. Bio bags not Bio Filters as advertised! BIO BAGS are only $13.74 thats a $6 riley off!
