So it's been about a month with my filter cartridge and I'm thinking about changing it soonish. I've been reading a bunch of stuff online about cutting the filter open and dumping the carbon out and adding new carbon...that seems a little extreme if you ask me...can't you just buy a new one and replace it? I have the Aquean Quietflow one. If you have any questions on what it looks like, visit this link where there are plenty of pictures.

picture down shows the bio-grid (blue) with the filter inside. So do I just remove the white floss filter from the blue grid and put a brand new one in or will that start a new mini cycle? Or do I do what the internet says and cut it at the top and replace the carbon part.
Anything else I need to know about putting a new filter in?
