While emerald-green water seems magical and tranquil out at sea, it’s not as aesthetic when your swimming pool starts reflecting that color. Green pool water is far from normal as it usually results from abnormal water pH levels or a chemical imbalance. To find out why your pool is green and how you can fix it, carry on reading this blog.

Why is My Pool Green?

Green pool water is not a normal trait. Usually, the murkiness is a sign that something is wrong with the pool’s filtration system and that you need to get it professionally cleaned. Nevertheless, take a look below to see some of the common reasons why this happens.

  1. Algae Infestation
    The most common reason for a green pool is algae. Algae are microscopic plants that tend to grow rapidly, especially in hot and humid conditions. So, if your pool starts to take on a green tint during the summer, it is probably due to an algae infestation.
  2. Low Chlorine Levels
    Chlorine is a primary chemical defender that fights off algae and other contaminants. If your pool does not get its usual dosage of chlorine or if the chlorine levels fluctuate, it can give way to algae growth. Regularly testing and maintaining proper chlorine levels is the best way to avoid putting your pool at risk.
  3. pH Imbalance
    The average pH range of your swimming pool should be around 7 to 8. If the scale tips higher or lower, it can significantly change the water’s alkalinity. This is because the pH level of your pool water plays a crucial role in its overall health. If the pH level keeps alternating, it might be a sign to contact a professional pool contractor for help.
  4. Poor Filtration
    Insufficient filtration and poor water circulation can cause the water to go stagnant, which in turn gives way to algae and mold growth. A well-functioning filter helps distribute chlorine evenly and eliminates debris. To avoid your pool from getting murky, regularly clean and maintain the swimming pool’s filtration system to keep the water clear.
  5. Lack of Maintenance
    Pool maintenance is by far the most important step of owning a pool. Hygiene doesn’t just apply to your bathrooms but also to swimming pools. Neglecting tasks like skimming the water, scrubbing the pool walls, and cleaning the pool floor causes dirt to accumulate. Leaves, grass, and other organic matter can float into the water and become nutrients for algae, which causes the layer of pool water to turn green.
  6. Environmental Factors
    Believe it or not, the weather and sunlight can also majorly influence the color of your pool water. Extended periods of sunlight without sufficient chlorine levels lead to algae growth. Additionally, heavy rainstorms can transfer organic matter into the pool, which only fuels the algae. Be mindful of these environmental factors and adjust your pool maintenance routine accordingly.

How to Treat a Green Swimming Pool?

The best way to handle a green swimming pool is by filtering the water and cleaning out the algae. To do this, you can install a filtration device or contact a professional pool contractor to settle the murkiness within the water. Once your pool is back to its original color, make it a habit to clean and regularly maintain the water to prevent the same situation from arising again.

In summary, if your pool is green, it could very well be due to algae growth resulting from pool negligence and lack of maintenance. To ensure your swimming pool retains its prime condition, feel free to contact Town & Country Pools at (281) 252-6337.
