New plumbing design for two tanks and sump.

[Douglas]

Here's my new plumbing design for incorporating my old display into my whole system. All three tanks (new, old, and sump, will be at three different levels of height. With the main display being in a different room. I didn't have a lot of people interested in purchasing my old display, so I'm going to keep it, and plumb it into the system. (will keep rock, and a predator). Looking for opinions to see if it'll work. Thanks.
