How to Clear Green Algaecide From a Swimming Pool
- 1). Test the pH using the pH test strip. The ideal reading for pH in the pool is 7.2 to 7.8, but when you have green algaecide in the pool, you need to have a pH reading of 7.2 to 7.4. Dip the strip in the water, pull it out and compare the strip to the color chart with the pH test strip kit. Turn on the pool pump to filter. If the pH is above 7.4, use muriatic acid. If the pH is already below 7.4, use a sequestering agent.
- 2). Fill up a bucket with at least 1 gallon of water. Use 6 oz. of muriatic acid per every 5,000 gallons of water in the pool if the pH reading is 7.6 to 7.8. If the pH reading is 7.8 to 8.0, use 8 oz. of muriatic acid per every 5,000 gallons of water in the pool to lower the pH. Add the correct amount of muriatic acid to the bucket of water.
- 3). Pour the acid solution in the deep end of the pool walking from one side of the deep end to the other side of the pool where the shallow end of the pool starts. Keep the solution off the pool walls and any pool fixtures.
- 4). Add a metal sequestering agent to the pool according to the directions on the package for the size pool you have to treat. The metal sequestering agent will clear up the green algaecide caused by the copper in the algaecide only after the pH is balanced.
- 5). Test the water hardness, chlorine and pH levels the next day and adjust the levels if needed after the pool water is clear.
