Yea, I've moved quite a few tanks in my past. I've gotten the totes for fish, totes for live rock and totes for corals.
Got 3 5g buckets for substrate rinsing, ran it clear, and thrown it back into the tank.
The rock is where the majority of your bacteria is at, thats the key stuff you don't want to get messed up. Make sure it stays wet. Once you've rinsed out the substrate with FW
, you've either rinsed away or killed whats in it, so your basically starting with new substrate anyways.
I've got 55g drums to make up water that I'll need, get it to temperature and SG
the day before, and pump it into the tank, after I have all the stuff in place. Leave a bit of room for the water in the totes, and your off and running.
