Ugh, sorry to hear the tank migration with the new sump/frag tank was so rough. I had a similar pain with our tank move on our smaller tank putting our fish/corals in a holding tank for longer than I wanted.
Looks like a beautiful tank and a nice system with a lot of volume. Who made your display? Did it have a stock overflow or did you DIY?
Best of luck. New setup seems great. Dong is a great resource both for coral and advice, definitely a great person to know while you're re-populating your tank.
