internal pump. i was looking at the eheim 1260 or 1262. Maybe a Mag 7? What you guys think about those choices? Gonna have a mp20 and mp10 in the display so flow shouldn't be a big concern and will probably Tee off to a reactor too.
+1 on the 1262 for reliable submersible pump. It's rated for 900 or so gph at 0' head so after all the restrictions and tee off, you'll probably get about 500 gph back into the tank.
