After three months im finally getting the ball rolling on setting up my 75gal. So far I've finished the sump and completed the drain line plumbing. I also purchased 30lbs of sugar sized aragonite, a skimmer, and filled the tank up with water. Below are some pics of what I've done so far.

Next week I'll be ordering the pumps for the return and closed loop. The week after that I plan on getting at least a small clean up crew and live rock. Lights will be the last addition before I start focusing on stocking the tank.
Some things that have changed from my original plan include the pumps and the skimmer. I went with a PCI NW250 over an ASM as they are built much stronger and offer the same perfomance. The pumps will now be a OR 2500 for the return (650 gph) and OR 6500 (1700 gph). Also, I decided to use less rock in the tank, so I will probably have close to 60 lbs of true live rock and only a little base rock.
