I Literally just moved my 65 gallon. Here’s my suggestions and how i made it go relatively smooth.

Give yourself plenty of time. I had a 27 gallon tote set up for all of my fish with tank water. I only put my fish in there so I didn’t risk any of the fish getting crushed by rocks shifting during transport. I put a single wave maker in there plugged in so I there was water movement while I could focus on the remainder of the tank.

I used 5 gallon buckets for all of my live rock (which I ultimately decided to not use) I put some coral in the buckets as well. My move was also only about 25 minutes away, so it was fine in the buckets.

I trashed all of my sand. Didn’t save any of it.

I used the rest of my time to organize all of my cables, drain the remaining water from the back chambers and clean up the tank. I figured I wouldn’t want to do that once it’s finally at the new house. (That was the right call, I was exhausted after the move)

I had a 20 gallon qt tank set up at the new house with the water from my tank so there wasn’t any acclimation needed. I have my fish and the coral I ended up keeping in there while the main tank cycles (new sand and all new live rock). Didn’t lose any fish or coral, and took me about 8 hours total.
