I ran a leak test on the frag system last week. That was the motivation to redo the stand pipes and create the overflow boxes.
I still need to make and install those boxes. I need to hook up three more major drain lines for the fuge and reactors in the main system.
I also am putting in a type of closed loop on the fuge. That's something I will have to describe and show once complete. It won't make sense without pictures.
That's about it for the main tank. Then, it's on the the QT systems.
Then, water mixing station.
Then, FWTO system.
I probably should do a leak test before cleaning up too much in case I need to make more PVC shavings.
Once I'm relatively convinced I'm done plumbing, I need to do a major cleaning of the room.
Then, build the light rack and hood for the main display. That's a big project because of space (and wife) requirements. Then, once I'm done crawling around inside of the display to build the light rack, I can finally run some saltwater through.
Oh, and lights, and electronics, and all of the other things I'm forgetting.
