Can I use household bleach to sanitize my pool?

Yes, but only if it’s plain, unscented bleach with no splash-less additives and the right concentration. Most household bleach is 6% sodium hypochlorite, so you’ll need roughly twice as much as pool chlorine. Avoid scented or “splash-less” types—they can foam and mess with pool chemistry. For regular use, just buy pool shock—it’s cheaper and more reliable.
