Quick guide to identifying algae types and clearing green pool water with proper chemical treatment.
Green water indicates algae growth due to insufficient sanitization or imbalanced chemistry.
Check pH, alkalinity, and chlorine levels. Adjust pH to 7.2-7.6 first.
Vigorously brush all walls, floor, and steps to break up algae colonies.
Add 2-3 times normal shock dose. For severe cases, add up to 10 ppm chlorine.
Run filter 24 hours until water clears. Backwash or clean filter frequently.
After shocking, add algaecide following product instructions for your pool size.
Once water clears, vacuum dead algae to waste if possible.
