Im thinking of adding a calcium reactor to my new setup and found this one here.(http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=14717&N=2004+113458)Ive never been able to use a reactor before because of space limitations. So I dont really understand how they work. I know I would need additional components (co2, ph controller,etc.) My first question is would a unit like the one above sit inside or outside of a sump??? If it sits out side how is water feed into the unit? And then how and where does the unit introduce the treated water back into the sump.
