Why is my Pool Still Green After Adding Shock and Waiting 24 Hours?
After adding shock to your pool and waiting 24 hours, you may be disappointed to find that the water is still green. Here are some possible reasons:
- Insufficient Shock Dosage: The shock may not have been added in sufficient quantity to eliminate the algae.
- Low Chlorine Levels: Shock oxidizes organic matter, but it does not increase chlorine levels. If the chlorine level is too low, algae can still grow.
- Organic Debris: Dead algae and other organic matter can interfere with shock's effectiveness. Vacuum or brush the pool thoroughly before adding shock.
- High pH: A pH level above 7.8 can make chlorine less effective. Adjust the pH to the ideal range of 7.2 to 7.6 before adding shock.
- Cyanuric Acid Buildup: Cyanuric acid stabilizes chlorine but can also reduce its effectiveness. If the cyanuric acid level is too high, additional chlorine may be needed to kill the algae.
