Why Is my Pool Water Green? - Swimming Pool Cleaning Las Vegas

Green pool water can be a concerning site. There is one main reason behind the green color, and that is the presence of algae. The color of the water can point to how recent the algae formation is. A lighter green shade means that the algae are very recent. However, a deeper green shade could mean a bigger and more stubborn problem. 

Contrary to this, other factors contributing to the green color could be metal oxidation or pollen present in the water if you live in a high pollen count area. If you want to know more about what makes your pool water green and what you can do about it, keep reading! 

Keeping Your Water Parameters in Check  

The first step to cleaning green pools, as recommended for swimming pool cleaning Las Vegas, is testing water parameters. The most important ones to look for are alkalinity, pH level, and free chlorine particles. 

Keep an eye out for these parameters by using test strips and liquid test kits. Low free chlorine can mean that the water isn’t sanitized and can quickly turn green. Having appropriate parameters can ensure that the shock treatment works efficiently.  

Scrub Every Surface 

Go over the pool surfaces with a bristle brush. Pay more attention to areas with visible dirt spots or little water circulation. Cleaning the pool with brushes and vacuuming up the dirt can prevent future build-ups.

Apply Shock Treatment for Algae

Shock treatment is the most crucial step when cleaning up green water. High concentrations of chlorine in the form of calcium hypochlorite are used in these treatments. The treatment works by removing different contaminants that may cause algae growth. The preferred concentration of chlorine for these types of treatments is 70%. 

Depending on the color of the pool, you may need to repeat the treatment several times. The deeper the color, the more times you should apply the treatment. Black green water is the hardest to clear, as the algae are present in large amounts. 

Your Pool Filter is Your Best Friend

After applying the shock treatment at night, it is recommended that you use the pool filter for 8 hours. Make sure the filter is working and in good shape. This way, your pool water will clear up quicker than just the shock treatment. If the water is blue, the water has been successfully cleaned. You can add a water clarifier to work with your pool filter at this stage.

Testing Water Parameters Again 

After the combination of shock treatments, pool filtering, and water clearing, it’s important to test the water parameters once again. Look out for pH, alkalinity, calcium hardness, and chlorine levels. If one of these parameters is off, add the appropriate chemical to balance out everything.
