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

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

Very good

Liked worked great

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

Love that there are more than one, had to figure out though how to put them together. Believe the ones which contain less than this amount, they are already put together. Ultimately, I just looked at the one which I was removed in order to see how to put it together in order to use. Arrived quickly and as described.

The listing is exactly what arrived.

Less expensive than buying at the store.

Works as advertised

Excellent way to purchase

Good.
