What Makes a Pool Turn Green?

Every pool owner knows the importance of maintaining crystal clear water. But what causes that drastic shift to a green hue? The most common culprit is algae growth, which thrives in water that isn't treated correctly.

In most cases, the presence of algae is due to a chemical imbalance in the water. Incorrect pH levels, low chlorine, and poor circulation can provide an ideal environment for algae. Furthermore, external factors like weather changes and environmental debris can contribute to algae growth.

While maintaining a proper chemical balance is crucial, it's equally important to clean your pool regularly. Failing to do so can lead to the accumulation of debris, fostering algae growth. Investing in a good filtration system can go a long way in maintaining your pool's health.

At Blue Orange, we offer professional pool services to help you keep your pool clean and free from algae. With our help, you can enjoy your pool without worrying about it turning green.

Is It Safe To Swim In a Green Pool?

Now, let's tackle the question that's been hanging in the air: Is it safe to swim in a green pool? The short answer is, it's not recommended. A green pool is a sign of algae growth, which isn't ideal for swimming.

According to a survey by the Centers for Disease Control and Prevention (CDC), 1 in 8 public pools in the U.S. was closed due to a health-related concern, with improper pH levels being a significant factor.

Algae itself isn't harmful. However, the conditions that allow algae to grow are also conducive for harmful bacteria. These bacteria can cause various health problems, from skin irritation to more severe infections.

Swimming in a green pool can also lead to other health issues. Eye and ear infections are common in people who swim in contaminated pools. In severe cases, people may experience gastrointestinal issues.

To put it simply, while a quick dip in a green pool might not be deadly, it's certainly not advisable. It's always better to resolve the issue and ensure your pool is clean and safe before diving in.

Preventing Your Pool from Turning Green

Prevention is always better than cure, and the same applies to your swimming pool. Here are a few steps you can take to prevent your pool from turning green:

  1. Regularly test and adjust your pool's chemical balance. A pool testing kit can help you keep track of pH, chlorine, and alkalinity levels.
  2. Clean your pool regularly. This includes skimming the surface, vacuuming the floor, and brushing the walls.
  3. Invest in a good filtration system. Run the filter for at least 8 hours a day, or as recommended by the manufacturer.
  4. Cover your pool when it's not in use. This will help keep out debris and reduce evaporation.

Treating a Green Pool - Step by Step Guide

Regular maintenance can reduce the chances of a pool turning green by 65%. If your pool has already turned green, don't panic. Here's a step-by-step guide to treating a green pool:

  1. Test your pool water. Identify what's out of balance and adjust the chemical levels accordingly.
  2. Remove large debris using a pool net.
  3. Shock your pool. This involves adding a high dose of chlorine to kill the algae.
  4. Brush and vacuum your pool to remove dead algae.
  5. Run your filter continuously until the water clears up.
