I didn't see the pool volume before. Did you add it as a sig? There is a tool called "The Bleach Calculator" that I don't use, but others do, that gives you recommended amounts.
But for chlorine, the formula is:
(1,000,000 / pool volume) * (Bleach Concentration as a decimal) * gallons of bleach = PPM of FC added. (FC means Free Chlorine)

Bleach concentration means "6%" bleach is 0.06. "12.5%" is .125

So 1,000,000 / 17600 = 56.8

56.8 * .06 * 1 (that is, one gallon of bleach) = 3.41.

That means a gallon of "Ultra Bleach" that's 6% strength will add 3.4ppm of FC to your pool.

A gallon of 12.5% will add 8.5ppm of FC in your pool.

I generally ball-park the adding Muriatic Acid (1 cup at a time), Borax and/or Baking Soda (1/4 box at a time), CYA usually is marked to indicate how many pounds of stabilizer will raise CYA a certain amount per x# of gallons.

Hope that helps
