With most filters I've used, the carbon needs to be replaced about once a month. Seachem recommends replacing Matrix Carbon every 3-6 months, depending on how dirty your water gets. (There's a detailed explanation on their web page.). If I can smell the water when I lift the top of the aquarium, I know it's time to rinse the filter and carbon. If it's been 6 months, I'll replace the carbon. The refillable bags are sturdy, so you can buy Matrix carbon in small or large jugs and refill the bag on a regular schedule. Matrix carbon and the Tidal power filter are the best available in my experience.
