Once again, I am saved by my glacial slowness, I've been considering replacing my old petsmart pond pump ( It's in a 4x4x2 marine box jammed into a dual 3.5" bay and will be 4 years old, January 17th 2005 ).
Looks like I'll be skipping a C-Systems pump.
I'm in no hurry to decide these things after all I'm still running a BeCooling Jagged Edge
