To lower the pH, add some muriatic acid or sodium bisulphate. To increase the pH, add sodium carbonate. [1] X Research source The ideal pH for pool water is between 7. 2 and 7. 6.
For light green algae, double shock the pool by adding 2 pounds (907 g) of shock per 10,000 gallons (37,854 L) of water For dark green algae, triple shock the pool by adding 3 pounds (1. 36 kg) of shock per 10,000 gallons (37,854 L) of water For black-green algae, quadruple shock the pool by adding 4 pounds (1. 81 kg) of shock per 10,000 gallons (37,854 L) of water
An ammonia-based algaecide will be cheaper and should work with a basic green algae bloom. Copper-based algaecides are more expensive, but they’re also more effective, especially if you have other types of algae in your pool as well. [3] X Research source Copper based algaecides do tend to cause staining in some pools and are the main cause of “green hair” when using a pool.
Brush slowly and thoroughly to ensure you cover every inch of the pool’s surface. This will prevent the algae from blooming again.
Set the filter to the waste setting if you’re using it to vacuum the pool. [4] X Research source
Turn off the pump and turn the valve to “backwash” Turn the pump on and run the filter until the water runs clear Turn the pump off and set it to “rinse” Run the pump for a minute Turn the pump off and return the filter to its normal setting Turn the pump back on
Lower the pH by adding muriatic acid or sodium bisulphate. Increase the pH by adding sodium carbonate. [6] X Research source Test the water again after treating it. The ideal pH is between 7. 2 and 7. 6.
Brush the bottom and sides of the pool thoroughly and vigorously to break through the algae’s protective layer. [7] X Research source
During the shocking and algaecide treatments, leave the pump and filter running all the time. [8] X Research source
After adding the algaecide, let it sit overnight.
After shocking the pool again, continue brushing daily for the next three or four days, or until the algae is gone.
When the garments and towels are dry, dry them in the dryer to kill any leftover algae. [12] X Research source

The ideal pool pH is between 7. 2 and 7. 6 The ideal chlorine level is between 1. 0 and 2. 0 parts per million The ideal alkalinity is between 80 and 120 parts per million
The pump and filter should run between eight and 12 hours a day during pool season. Brush and vacuum the pool every two days. Clean and sanitize pool equipment and toys every one to two weeks.
