Rivers to Reef says:  These bags recommend a monthly changing, but we say to just replace it when it gets clogged. This is usually dependent on the bioload of your tank. It might take 3 weeks, it might be 8. Just keep an eye out, and when the water starts to overflow back into your tank it's time to swap them out.
