I am getting a water softner???

On Dec 22 I am having a water softner installed. I had 14 grain hardness.
What would be the best method to acclimate the fish to the new softer water
condition, or should I use the hard water from an unconditioned outside cold
faucet to service the tank with. Since it will be the dead of winter,
should I also take this "outside hard" water and store it in the house for
a few days to bring it up to temp or mix warm softened water with it.
Normally, I use a thermometer to adjust the temp from the faucet and then
add water condtioner before refilling the tank.

My fish stock is as follows:

2 Glass Catfish (Large, -P 1/24/04) (Small, -P 2/5/2004)
