Congratulations!

How long to fill depends on the flow from your tap. You should have about 12,000 gallons so if it's 1000 gallons a minute, 12 minutes!
100 gallons/minute, 2 hours. 20 gallons a minute, 10 hours, etc.

I like to add bleach as soon as I have a foot of water, dribbling it slowly all around the pool, but NOT on the liner! A single gallon of bleach will be fine for the first fill and gives you some protection. You MAY want to prepare a dose of CYA in an old stocking also. Figure to use no more than HALF of what they recommend for your 12,000 gallons. Even a 1/4 is fine--it's easy to add more, hard to get rid of. Testing will wait till the pool is full.

One thing to check. Make ABSOLUTELY certain the maximum flow the filter can tolerate is greater than the maximum flow of the pump. If it's not, either get a bigger filter or a smaller pump.
