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

Liked worked great

Took two weeks to get to my house, but it came in damaged. If you wash them out when they are dirty they are very cheap.

The filters are excellent for keeping the tank looking nice and clear!

company is a cheat

Fast delivery will order again

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.

have to put the filter and charcoal in the sleeve. Not hard, but weird.

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.

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

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