I was at the LFS and the owner recommend looking into a c02 reactor, anyone have any experience with one compared to a full c02 set up?

I think the posters above are poking fun at your nubieness!
A CO2 reactor is a way of putting CO2 into your tank water. It is only a small part of a CO2 system and cannot work by itself. You need a supply and control system as well. Do some research.
