Works great
fit like they should, some people don't like this filter in the reviews but they do a decent job and are easy to take to take out and rinse.

Can’t find these in stores any more. Happy I could find them on Amazon. They fit my aquarium filter perfectly

Not for my fish
I'm using this product for myself in the shower. I found it will remove the epidermis cells with ease. Cleaning up the product is a jif. I believe based on these facts for me, probably then, it would also make a good product for cleansing the tank.
