Here's what I'd recommend:

1. Get a cheap local OTO/phenol red test kit (yellow/red drops)
2. Buy a box of borax (detergent section of Walmart) and a spa container of pH Down or similar.
3. Buy a gallon of PLAIN household bleach.
4. Dump and refill your pool
5. Add 1/4 cup of bleach
6. Test the pH and chlorine. Chlorine should be ~5 ppm (dark yellow). PH should be what ever.
7. Add 1/4 cup of borax if the pH is less than 7.2. Add 1/8 cup of pH Down (dry acid) if the pH is above 7.8
8. Swim.
9. Check pH and chlorine nightly. Add pH adjustment doses as above -- just ONE dose per day.
10. Add chlorine dose each PM unless chlorine is high (dark yellow)
11. Replace water every 2 weeks or 10 uses.
12. Do NOT allow sick kids in the pool - you can't sanitize such a small pool adequately to keep one kid from infecting another.

The process above should be cheap, easy, and keep the pool fairly clean. But it will not protect one swimmer from another one.

Pooldoc - Could I trouble you to provide the recommendations and chemical doses for my 1180 gallon pool please?
