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

Just what we needed for our filter.

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

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.

Very good

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.

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

Liked worked great

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

company is a cheat

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.
