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

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.

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.

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

Good filters

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

Easy to use and fish are doing great

6 filters that fit a 10 gallon filter.
