for a 30K gallon pool, pH=7.0; FC=0.8; CYA=50:

1. Add 2 gallons of bleach immediately (4 ppm) and 6 gallons (12 ppm) tonight.
2. Add 1 box of borax SLOWLY via the skimmer.
3. Retest chlorine and pH in the AM. If FC>10 ppm, you are probably OK, and can live with daily 4 ppm (2 gallon) doses till you have another plan.
4. If the pH < 7.4, repeat daily borax doses till it is above 7.4.
5. Read the Best Guess chart page, so you can get an idea about how you may want to operate your pool for the rest of the summer.
6. Test your calcium levels, to make sure they are not high enough to be a problem.
