Moving Advice 5 year old tank

[StretchHex]

In the next month I'm moving into my new house. I have a 150Gallon tank and it's been going for a long time. The tank is under stocked with 6 fish and two plate corrals so I will probably setup a temporary tank for them while I do the move. Wondering if I should just reuse the sand or what, I haven't touched the sand in a while it's about an inch thick. The rock has its issues too, cactus algae sprouts out from it but it's under control but I have a severe aiptasia out break which is basically just out of control. Not sure what to do here. I won't have to move the tank on the same day as my stuff but it is gunna be busy. What should I do? Thx
