Review on Fluval C2 Replacement Poly Foam Pad - 3-Pack by Ashley Martinez

This is a direct replacement for the C Series filter pads that come with the filter. They are the same size, thickness and made of the same material. The only reason I took off a star is because a last one is yellow in a section on one side. So I only have 2 pads available. If they weren't so cheap I would probably go back, but it really isn't worth it. They last a very long time, no need to replace monthly bills as instructed in the instructions. Simply rinse in aquarium water with every water change.
