I would aviod running CLR through your system. I ran it through my last system to try and clean it out, and it made my pump develop a rattle (a ViaAqua 1300 that had run for a year without making a sound). It's possible that it was something other than the CLR that caused my rattle, or that CLR eats/reacts with some material only found in ViaAqua pumps, but I'd say be cautious and use at your own risk.
