How to Clean a Green Pool: Step-by-Step Guide
Follow these steps if your pool has turned green to restore its clarity and make it safe to swim again.
1. Test and Balance the Water
You have to test the water before adding chemicals. Chlorine, pH, and alkalinity levels can be checked by a pool test kit. pH should be between 7.2 and 7.6 for chlorine to work effectively.
2. Shock the Pool
Shock to clean a green pool with chlorine is the most effective way. Use 3-4 times the normal amount of shock for severe cases. Add it in the evening and let the filter run overnight to allow proper circulation.
3. Brush and Vacuum the Pool
Once the chlorine starts killing algae, it will settle on surfaces. Brushing the walls and floor helps loosen it. Vacuum the debris to prevent it from clogging the filter and keep the water from turning green again.
4. Run the Pool Filter Continuously
Your filter is your best ally in clearing cloudy green water. Run it 24-48 hours non-stop, backwashing or cleaning the filter frequently to remove dead algae.
5. Use an Algaecide (Optional)
If algae persist, an algaecide can help eliminate lingering spores and prevent regrowth. Use it after shocking and filtering for best results.
