Common Problems with Pool Water – and Their Solutions

Common Problems with Pool Water and How to Fix Them

Cloudy, green, or discoloured pool water is often due to an imbalance in water chemistry, poor circulation, or a filter that needs attention. Here you will find a clear troubleshooting order for the most common problems.

Cloudy Water

Cloudy water is one of the most common problems and often indicates insufficient filtration or poor water circulation. In addition, incorrect pH levels and insufficient levels of disinfectant can cause the water to become cloudy and uninviting.

Solution

• Clean or backwash the pool filter regularly to maintain its efficiency.

• Ensure that the water circulates properly with the help of pool pump, which is essential for an even distribution of chemicals and filtration of particles.

• Test regularly and adjust the pH levels to the recommended range of 7,2 to 7,6 for optimal water quality.

• Maintain appropriate levels of disinfectant to effectively combat bacteria and algae.

Algae Growth

Algae thrive in stagnant or chemically unbalanced pool water. The most common types are green, yellow, and black algae, all of which require specific treatment methods to be effectively eliminated.

Solution

• Shock the pool by adding a high dose of chlorine to quickly eliminate existing algae growth.

• Brush and vacuum the pool's surfaces regularly to remove algae spores and prevent their return.

• Ensure proper water balance and disinfection to prevent future algae growth.

pH Imbalance

The pH level in pool water is of utmost importance for both the effectiveness of disinfectants and the comfort of swimmers. Low pH can lead to corrosion of pool equipment, while high pH can cause deposits and reduce the effectiveness of the disinfectant.

Solution

• Test and adjust the pH levels regularly with suitable products.

• Use pH-increasing or pH-decreasing agents as needed to achieve optimal balance.

• Aim for a pH value between 7,2 and 7,6 for ideal conditions in the pool.

Chlorine Problems

Chlorine is the primary disinfectant used to eliminate bacteria and algae in pool water. Problems arise when the chlorine level is too low, resulting in ineffective sanitation, or too high, which can cause irritation to swimmers' skin and eyes.

Solution

• Test and adjust the chlorine level regularly to ensure optimal levels.

• Use stabilisers to protect the chlorine from breakdown caused by the sun's UV rays.

• Shock chlorinate the pool after heavy use or during algae outbreaks to restore water quality.

Calcium Hardness

Calcium hardness refers to the concentration of calcium ions in the water. Low levels can lead to corrosion of the pool's surfaces and equipment, while high levels can cause deposits on these surfaces and in the equipment.

Solution

• Test and adjust calcium hardness levels regularly to maintain balance.

• Use calcium hardness increasers or decreasers as needed to correct the levels.

• Maintain levels within the recommended range of 200-400 ppm for optimal conditions.

Stains and Discolouration

Stains can develop on the pool's surfaces due to metals, leaves, or other organic matter. Discolouration can also occur as a result of chemical imbalances or inadequate water circulation.

Solution

• Use stain removal chemicals or clarifiers specifically designed for pools.

• Clean the pool's surfaces regularly and remove debris to prevent new stains.

• Address underlying water balance issues to prevent future stains and discolouration.

High Total Dissolved Solids (TDS)

TDS represents the total concentration of dissolved minerals and contaminants in the water. High TDS levels can be due to various factors, including excessive use of chemicals, mineral-rich top-up water, or evaporation.

Solution

• Partially drain and refill the pool with fresh water to reduce TDS levels effectively.

• Use a water softener if high mineral content in the top-up water is a recurring problem.

• Practice water conservation to minimise the need for frequent top-ups, which can contribute to high TDS levels.

Conclusion

Maintaining a flawless pool requires precision and regular attention to water quality. By understanding and addressing the most common pool water problems, you can ensure that your pool remains a source of enjoyment rather than frustration. Regular testing, proper chemical balance, and routine maintenance are the keys to a clear and inviting swimming pool. Dive into the world of pool care and let your oasis shine!
