Looking good. Good size tank.
As for the sump, Sell it. Make your own.
Include a DSB
(Good way of removing nitrates if set up right - Needs flow.)
Macro Algae (Good way to harvast nitrate out of your tank)
And a good sized/brand skimmer. Also a couple of baffles to get rid of them bubbles.
Make the sump as big as you can, The bigger the better. If you want to get full into reef, Make a Frag section too. But before you make the sump, Make sure you take into account equipment storage. Chiller, Reactors, Ballast and what not.
Great start, Will tag along.
