Things You'll Need:
- Pool vacuum
- Pool brush
- Chlorine shock grains
- pH balancing salts
-
Step 1
Use a pool vacuum to remove as much algae as you can. Take off all the excess algae with a long pool brush. Purchase a chlorine shock solution and follow the manufacturer's directions for use.
-
Step 2
Take a water bucket (about half full) and mix in the required amount of coarse chlorine shock grains. Add 1 pound for every 10,000 gallons of water. To tackle a severe algae problem, add 1 pound for every 7,500 gallons of pool water.
-
Step 3
Turn on the pool filter and add the shock mixture to the pool. Let the filter run for 24 hours and observe the pool at regular intervals during the day. If you don't observe any significant improvement, add an increased dosage of the chlorine shock to the pool.
-
Step 4
Clean the filter periodically to remove any trapped algae. Monitor the pool carefully and if the algae turns gray or white, falls down to the bottom or starts to float on the water, remove it with the pool vacuum and the skimmer rod.
-
Step 5
Test the water for a stable pH. The pH should be between 7.2 to 7.6. Add pH balancing salts or liquids as needed. Let the chlorine level return to the range of 1 to 3 parts per million before using the pool again.
