Assuming your ammonia test is valid, THEN

1. Use borax to raise the pH to near 8.0.

2. Add PLAIN 8.25% household bleach each evening at the rate of 1.5 gallons per 10K pool gallons. Continue until combined chlorine levels is less than 1 ppm. Postpone a dose anytime the free chlorine level is greater than 10 ppm

3. Order a Taylor K2006 (test kit page with links to Amazon in my signature block -- these kits can NOT be purchased locally!) ASAP. Report test results ASAP.
