Yup. Regular, ordinary, unscented, non-foaming Bleach, either 5.25% concentration or Ultra (6%) concentration. In case you are concerned, pool stores sell "Liquid Chlorine, 6%" and it is IDENTICAL to Ultra Bleach.
One gallon of 6% bleach should raise your FC level (Free Chlorine) by 3 to 3.5ppm.

That's what our B-B-B Method of pool care is all about: Using Bleach, Borax and Baking Soda as your primary chemicals (plus a few others, but saying "BBB" is catchier! )
