A little guessing but your high pH probably contributed greatly to that milkiness. I would:

1. download mwsmith2's calculator from any of his posts.

2. use it to calculate and add enough muriatic acid to get your pH to 7.2

3. Figure out a way to test for CYA and post your numbers back up.

4. Be prepared to add quite a bit of plain ole' Clorox but we need to see your second set of numbers including the CYA before we recommend just how much Cl to add.

5. Any other pool store chemicals you put in there will cost you some bucks, may not help, and will really confuse us on the forum.
