Pool water is green

[PoolDoc]

1. What drops kit?

2. Get a cheap local OTO / phenol red kit and 12 gallons of PLAIN 8% bleach from Walmart or equiv.

3. Add chlorine in 3 gallon doses each PM, till the green turns gray or brown. Test chlorine beginning the 2nd evening; skip chlorine dose if OTO test result is orange.

4. Stop adding other chemicals unless pH is below 7 or above 8. Only test pH when OTO result is medium yellow or lighter.
