So it has been a while since I've posted an update to the thread. A lot has happened over the last few months that kept me from making the progress that I would have liked on the tank, but you have to roll with the punches.
This is a picture of the basement with the epoxy floor completed and the main sump stand in place. The floor came out nice, but I did notice that in different areas of the basement the epoxy was absorbed by the concrete differently. Overall I am happy with it. It is a basement after all.
Next up was an adventure in plumbing. I probably spent a good 8-10 hours working out a plan to keep things as symmetrical as possible to ensure that each side would flow equally.
My dad gave me a hand when my parents were vising over Thanksgiving. It was helpful to have another set of hands to hold things together while the glue was setting on the pipes and fittings. I finished up the plumbing for the basement sump over the next week and a half or so.
Since it was holiday time, I decided let things sit until January as I didn't have the time I wanted to double check things and I didn't want to have any leaks while I was visiting family for the holidays.
About the second week of January I started filling the sump with water. I transfered water from my storage containers into the sump saturday morning and started making more RO. I came back down into the basement to find puddles on the floor.

The used tank I had acquired for the sump had sprung a leak and I had no idea from where.
I considering draining it and reapplying silicone to the entire tank. I went back and forth on this for about and hour and decided to check the pricing on a new 75 g for the sump. One of our local fish stores, Realm of Pets, had a very good price on the tank, so I had them order me a new tank for the sump. The down side was that I lost about a week and a half. :sad2:
Fast forward to the next closest Saturday, I pick up the tank, drilled the side for the bulkhead fitting, sealed everything back up, and started where I left off..... filling water
Let me just say that filling a tank takes a LONG time. Especially when you don't have a float valve set up on the water storage system and you are only letting the water run while you are home. It took about a week, but I got everything filled up to start the "fresh water" check.

Sump and return plumbing:
Manifold and DC8 for the AC3. This is probably not going to be the final resting place for the DC8, but I put it on the board as a starting point.
