Review on 🔍 Fluval C4 3-Pack Poly Foam Pads for Enhanced Filtration by April Russell

Works great. I am very happy with it. Makes water nice and clear. One thing I want to mention is the warning to change them every 2-4 weeks. I changed them once about a month later and the mesh bag came undone when I pulled it out of the filter. It wouldn't be long before that bag fell apart and all those little black grains of carbon ended up on top and mixed with my beautiful white sand and were impossible to separate. Other than that they work great and overall the Fluval C4 is a great filter.
