Thanks Cal Newbie;

Jerry's PF is 70. This means a gallon of PLAIN 6% household bleach will add about 35 ppm of chlorine to his pool, since there's about 1/2 lb of chlorine gas equivalent in a gallon of 6% bleach. With no stabilizer, adding 1 cup of bleach before and after each use interval AND 2 cups in the evening should work.

Jerry, if you'll do that, you'll keep your pool reasonably safe. However, the Intex pools have minimal filtration capability, so you there's no room to skip doses. Get the test kit and make SURE you add 2 - 4 cups of bleach to the pool EACH evening after everyone has finished using it. Keep in mind that, without stabilizer, the chlorine you add will be gone in an hour or less of full sunshine.

Pour the bleach in where the water comes into the pool, and keep people out of the pool for 2 - 3 minutes after you add bleach.
