Review on 🔌 Premium Penn Plax Cascade Hang-on Power Filter Replacement Cartridges (3-Pack) - CPF34C3 by Kathy Miller

Warning I did NOT receive what was pictured in the post! I received an individual package. The filter was much thinner than the shell. Also, charcoal leaks out all the time. I washed it as usual, but the running water did not go away. You might be lucky and get what is shown in the photo. However, if you don't do this, you will need to replace the trash can filter. Strongly disappointed!
