How to upgrade a tank?

[yellowworld]

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!
