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

These fit perfectly and the price is great

I have a 39 gallon tank for my Mr. Franklin. He is a dick and kills off his friends. I used to use honemade filter bags yet ran out.

I like my filter that why I buy it its cheaper then store

Is working so far

Works great

They say filter should last several weeks, barely lasts several days

I get twice as many at this price compared to what I was paying in the store.

Awesome Find

Available

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!
