I see what you're talking about Mike. I had been basing a lot of my plumbing off sidewinder770's layout and he had his all together (pump feeding all media). With our DIY Calcium reactor I didn't want to change the pump (feed to it) so I just dropped it into the sump input area. Having it feed of my return pump would fix my "what kind of pump" do I need to get for the media. I can still keep the pump for the Calcium reactor if I wanted. I'll draw up what I think you're saying and a few other changes I've been thinking about today and post later.
Thanks everyone for the comments.
Here are the threads and sites I've really have looked at for my build (or worked directly with - thanks Mike and Melev) - just to give others different ideas:
