Glenn has you started but let me tweak it a bit. Do not add all this at once or you will have a cloudy pool!!! Also, use Borax to raise pH, baking soda to use alk, or washing soda to raise both at the same time. But, certainly don't put 15 lbs. of anything in the pool at one time. Small doses and gradually get to targets. By the way, it is ok to add Borax and baking soda one after the other.

I also would not use cal-hypo. It is a vinyl pool and thus doesn't need calcium. Cal-hypo can cloud the water up. I'd just stick with bleach. Take it up to shock level and try and hold it there.
