I need to know when I should change my filter cartridge. The one I have has been in there for like two months now, and it's really dirty. However, I know that there are many beneficial bacterias in it. Imagine, one time my cleaner shrimp's old scale got sucked into it. I don't want to remove it, but if not my filter will not function properly. What do I do? I tried to clean it, but those brown stuff doesn't seem to change a bit. It's still there and it's still dirty. Help? Get a new one? If I need to get a new one, how often should I do that?
