A basement sump is cleaner, makes water changes easier, everything is just waaaay easier. I converted after 2 years.
Running a CL pump in the basement will nto affect its performance that much. The pump still sees no static head pressure, only the pressure induced by the pipes. Use at least 1.5 inch pipes and you will be pretty good. Use 2 inch pipes and you will be rockin. The pump IS NOT pumping water up only recirculating.
I will expand much more when I get from holidays if you like, for now I have to go.
