I'm assuming you'll just let the overflow handle the RO/DI filling of the sump. It's one way to non-pressure test your plumbing fittings.

If only I had all my plumbing done. I shorted myself two necessary pieces when I ordered from Savko. I am missing two 1.5 --> 3/4 bushings for the plumbing manifold and they won't be here until tomorrow. Unfortunately these are not something that HD carries.
If I did my calculations right, when I get home tonight the water level should be a couple inches short of the two holes for the returns. I will move the RO/DI to the sump and start adding a bucket of salt into the display tank. I will then set up the Vortech to get the water moving to help mix it up.
After the missing plumbing parts arrive I will finish off the plumbing and get the whole thing circulating for a few days before I start to add my rock this weekend, probably on Sunday :biggrin:. Once the rock is in place, I will let it sit for about three weeks before I start to stock it .
