Personally, I would take my time setting it up, and would do a leak test for a week or so before doing anything else.

good point. I may end up doing that.
 
Why not use the old water? If you have been doing regular maintenance on the old tank, using the 70 or so gallons in the new tank and adding the rest new is essentially a 55-60% water change. A complete water change can shock your fish.

I actually do 2 or 3 water changes a week.

A better question would be: why use the old water? We change that stuff for good reasons; here's a chance to get a fresh new clean start. Why settle for a 60% change when the same effort in this case gives us a 100% change?

The OP is doing regular water changes now, so his fish are presumably living in decent quality water. If they were in a tank that had never seen a water change and their water was highly polluted, then it is possible that a complete change, even into cleaner, better water, might be too abrupt a change. If their tank water had been tinkered with to produce an extreme change in pH or hardness, then caution would definitely be advised. But I have never had or heard of fish experiencing a negative reaction to the type of water change we're discussing here. I wouldn't use the old water any more than I would modify my bathroom toilet to do only a partial flush, and for the same reason. I want that stuff gone.

I would use the old water. Jjjohnwm would use all new water. OP, do what you are comfortable with.
As for the toilet analogy, I have one of those toilets that has two buttons- one for solids the other for liquids. Both buttons accomplish the same thing.
 
I would use 100 % new water dosed with Prime and Stability daily until your tank is cycled. Moved your cycled filter and any decor from your old that you plan to use, wait 24 hours and add your fish. There is no beneficial bacteria in the water column so when you move old water from the other tank all your doing is adding old water.
 
New tank is up and running. Been 24 hours.
Only one casulity and has nothing to do with water. It is a natural jumpy fish. I was in the middle of transporting other fish into the tank and my uncle must have spooked it and it jumped about 12' in the air and landed hard on my bucket. Poor thing did a death roll and died. Lost one of my flagtail prochilodus! I raised him from 2-3'' to 5-6'' and now am left with 2. hopefully these 2 don't fight they were raised together and are in a big tank now so praying.
Will upload the video here in a second.
