Review on 🐟 Penn-Plax Cascade Submersible Internal Filter Replacement Carbon Cartridges (2 Pack) – Effective Chemical Filtration for Aquariums: Freshwater & Saltwater by Jenna Morocho

I was not satisfied with the purchase but that is not the fault of the product. I wasn't paying attention when purchasing this product and ended up buying a size too small for my filter. So if you're looking for a replacement, make sure you get the right model and size. I would return it if it wasn't. t because my smartass opened the product packaging before I compared the filter sizes. Lesson learned.
