I'm currently plumbing my closed loop for my 180g and was wondering the best way to mount my external pump. I have the option of mounting it vertically or horizontally, vertically there would be a 90 elbow on the return (output) side of the pump--- horizontally the 90 elbow would be on the drain (input) side. Does it makes difference either way? Would there be too much stress on the elbow joint with 1700gph flow? Would there be a greater reduction of flow depending on where the 90 elbow was?
Thanks
