    PoolDoc has a writeup on this subject that I have been searching for hours to find, I'll post the link if I ever find it.

    I also have a 500lb filter and 2spd pump. spill over spa. On high or low speed I don't get sand in the pool. Pumps some out during backwash. Filter reads 22psi on high speed and 6psi on low.
