Tank swap - advice please.

Agreed, move everything then I even went one step further and boiled water to kill everything in the sand let the sand sit for 5 min while stirring, then I dumped it in my new tank. With 40lbs of LR you have plenty of bacteria to start spreading in your new tank.....keep in mind you may i say may have a small spike but with a few water changes it will settle down. That's how i did it and only my opinion though.
