3. Check the water pH value

If you want to remove more of the yellow algae and keep your swimming pool clean, you should test the alkalinity level. You can visit your local home supply store or Waters Choice to purchase a swimming pool test kit.

Using this kit, you can sample the swimming pool water, test, and find immediate results on your swimming pool chemical composition. You can also send the sample for analysis from a lab. Ensure the pH level of your swimming pool reads between 7.4-7.6. The alkalinity level should range between 120-150ppm. If the pH level is out of balance, you should call a professional for assistance.

4. Pool shock your swimming pool

You can also pool shock your swimming pool to keep the right level of alkalinity in your swimming pool. Take a 5-gallon bucket, fill it with water and mix with a pound of pool shock. Stir the mixture to obtain a fine paste, and then pour it inside your swimming pool. 

Pour the pool shock on every side of the pool, including the middle. You should use at least 3 pounds for every 10,000 gallons of pool water for the best results with pool shock.
