I don't know how many gallons your pool holds, but you're going to need to keep your Cl level at 1-3 ppm until you get some stabilizer in the water, which is going to be at least a week. Without stabilizer, you're going to have to add the bleach daily. Here's a link to the bleach calculator a lot of us use (credit to forum member mwsmith for the calculator) to figure how much bleach to add. http://home.earthlink.net/~mwsmith70...achCalc262.exe

Change the settings to imperial, then enter your pool volume in gallons, put 6% in for strength, put 1 in for ppm desired, and hit calculate--it'll tell you how much bleach to put in to raise your ppm by 1, and you need to keep 1-3. It also performs other calculations that you can use to help balance your water.

I would probably buy 5 or 6 gallons of bleach off the bat, and then you can always get more when needed. Use the plain, unscented, generic kind. If you use Clorox brand, make sure it's not the new stuff with the added whitening ingredient.
