Rated 4 out of 5 by aquarist91 great product
I buy this kind of filter cartridge because I have a Topfin 15g aquarium kit. Due to the new aquarium so I had to add double dose of benefit bacteria which resulted in cloudy water. And this filter cartridge made the water crystal clear again after a few days. I highly recommend this product. My only complaint is it's often out of stock in store and not sold online.
