I bought some Marineland Diamond Blend activated carbon with ammonia fighting crystals for the extra slots in my filters. How long is this stuff good for before it needs changed out?

Couldn't afford the one with scrubbing bubbles too, huh?
Seriously tho...
Before I recommend not using the carbon...
Do you have problem that you need the carbon?
Changeout depend on the efficiency of your filter and the bio-load of the tank. Two weeks to two months is about right tho.
