100% activated carbon filtered=bad?

[JDJP]

I have an 80 frag tank plumbed into my 350 gallon system. It's connected through anactivated carbon reactor. I've had the carbon out of it for a couple weeks, but am going to throw some fresh carbon in there tonight. I'm wondering if there are any "good" or necessary things I'd be stripping from the water being that 100% of the return to the frag tank is passing through carbon. I think there are some trace elements that get absorbed by carbon... anything else?

Don't worry about it.

I don’t think there will be any special issue.
