6-Pack, Size B, Rite-Size Cartridge Refills

Exactly what I needed for our fish filter.

Excellent for Aquariums

Satisfied. Used many years

Awesome Find

Fish died a few day after install

This was a fair price for the exact filter I needed. I like the fact in came in a 6 pack, which will last me awhile. Thanks!

Performs the exact function described. Works very well.

Filters don’t last more that a few weeks but filters very easy to change out and fairly inexpensive.

Exactly what I expected. Cheaper than our local pet store

Works well, good value
