activated carbon to filter hydro water?

so i was thinking getting some carbon and customizing my reservoir with a aquarium/fish filter.

has this been done before? any ideas what it will do to the water? i assume keep it clean and smelling fresh?

I would think that this would filter out nutes.

I have seen people using filters before but they were also the people that didnt belive in changing the res water! I was also thinking it may take out the nuts but who really know's! Give it A try on another system.

I've read about people using "bio filters", but a carbon filter will remove nutrients.
