What do you if just filled a above ground pool and it turns green right away so i shocked twice then put algaecide chlorine tabs still is the chorine off charts?

Test the pH level of the water. The ideal pH level for a pool is between 7.2 and 7.8. If the pH is too high or too low, it can affect the effectiveness of chlorine.

Continue to run the pool pump 24/7 to circulate the water and distribute the chemicals evenly throughout the pool.

Try adding a metal sequestrant to the pool water. Metal sequestrants can help to bind with metals in the water, which can contribute to the green color.

Brush the walls and bottom of the pool to remove any algae that may be growing.

Rinse the filter regularly to remove dirt and debris that may be trapped.

If the green color persists, you may need to shock the pool again with a higher dose of chlorine. Follow the instructions on the chlorine product label carefully.

Continue to monitor the chlorine and pH levels regularly to ensure that they are within the ideal range.
