I was looking at these DCP pumps for my for a 75Gal with a 20Gal sump build, need some advice, should I go with the 6500 or the 8000? The tank will be plumbed with two 3/4" return lines, since I don't know exactly the head loss has leaning towards the 8000. Also there will be no manifold since I will be running a full syphon overflow.
Any advice will be appreciated.
Thanks,
