Important Carbon Media Note

Fluval Carbon Foam provides mechanical and chemical filtration, but it is not a replacement for biological media. Activated carbon can become exhausted over time and should be replaced rather than reused indefinitely.

For reef aquariums or aquariums with sensitive livestock, always check the product packaging and monitor water parameters carefully before using chemical media.
