Can I get away with an internal pump?

[Reef Pilot]

The Sedra 20000 is an excellent pump for high head pressure, much better than the Mag pumps (which I have also tried). I have had one in my basement sump, pumping upstairs to my main display running for 6+ years with no problems.

They put it on sale sometimes.

It actually runs two tanks (another one downstairs) as well as a couple reactors, all off a set of Ts in the sump. And always starts reliably after a power outage (unlike the mags).
