• Begin setup of new tank, avoid any uncured rock, add new sand, add new water
• Let the new tank settle for about 24 hours
• Plumb new tank into 100 gallon viva common sump, run for a few days.
• Transfer over livestock
• Disconnect 100 gallon
• dismantle 100 gallon and apologize to your other.

The last step is key!

This is pretty much your only option unless you want to by a whole bunch of heaters for all the rubbermaids you are going to need. I am actually doing this myself tonight or tomorrow, though with a 50 gallon. I bet if you got 3 friends to come over you could all move the 100G.

I have to agree with steve and sphelps they are both on the right track, I would tank our maybe a 3rd to half the water and quickly slide it out of the way and then put the water back (your going to need a few ppl to help out there and at least 5 rummer maids for the water) the start your set up with the new tank and then follow sphelps directions after that

Good luck!
