Need Some Advice On An External Filter

carbon removes chemicals in the water, but i've run without it for years... and if you remove them then there is extra space for foam media!

I make do with the extra flow rather than replace with sponges. The 1200's hold so much media anyway that there really is no need to add anything else.
