Trouble in the Waters: Common Pool Problems Unveiled

April 22, 2024


Maintaining a clean and properly functioning swimming pool can sometimes feel like a never-ending task. From balancing chemicals to filtering out debris, there are a multitude of factors that can impact the quality of your pool water. In this blog post, we’ll discuss some of the most common pool problems that pool owners encounter, as well as provide tips on how to prevent and address these issues to keep your pool in top condition.

Algae Infestation

One of the most common pool problems that pool owners face is algae infestation. Algae are microscopic organisms that can quickly multiply in warm, stagnant water, causing green, slimy patches to form on the walls and floor of your pool. Algae growth can be accelerated by poor water circulation, inadequate filtration, and improper chemical balance. To prevent algae infestation, it’s important to regularly test and balance your pool water, ensure proper circulation through regular pool maintenance, and shock your pool with chlorine regularly to kill any existing algae spores.

pH Imbalance

Maintaining the proper pH balance in your pool water is essential for keeping the water clear, clean, and comfortable for swimmers. A pH level that is too high or too low can result in a range of problems, including skin and eye irritation, corrosion of pool equipment, and inefficient sanitization. The ideal pH level for pool water is between 7.2 and 7.6. To prevent pH imbalance, test your pool water regularly using a testing kit and adjust the pH level as needed using pH increaser or pH decreaser to keep it within the recommended range.

Chlorine Deficiency

Chlorine is a key component in keeping your pool water sanitized and free of harmful bacteria and contaminants. A chlorine deficiency can lead to cloudy water, algae growth, and an increased risk of waterborne illnesses for swimmers. Factors such as high temperatures, heavy rainfall, and high bather load can deplete chlorine levels in your pool. To maintain the proper chlorine levels, regularly test the chlorine levels in your pool water and add chlorine shock or tablets as needed to ensure that the water remains clean and safe for swimming.

Calcium Buildup

Calcium buildup, also known as scaling, can occur when hard water minerals such as calcium and magnesium accumulate on the walls and floor of your pool, leaving behind unsightly white deposits. Calcium buildup can be caused by high levels of calcium hardness in the pool water, as well as an imbalance in pH and alkalinity. To prevent calcium buildup, regularly test and balance the calcium hardness levels in your pool water, brush the pool walls and floor to remove any existing deposits, and consider using a calcium descaler to dissolve stubborn buildup.

Clogged Filters

Pool filters play a crucial role in removing debris, contaminants, and impurities from your pool water, helping to keep the water clean and clear. Over time, pool filters can become clogged with dirt, leaves, and other debris, reducing their effectiveness and preventing proper water circulation. To prevent clogged filters, it’s important to regularly clean and maintain your pool filters by backwashing them, replacing filter cartridges or filter media when necessary, and ensuring that the filter pump is running efficiently.

Leaks and Loss of Water

Leaks in your pool can lead to a loss of water, increased water bills, and potential damage to the pool structure and surrounding area. Common causes of pool leaks include damage to the pool liner, plumbing leaks, and cracks in the pool shell. To detect and address pool leaks, regularly inspect your pool for signs of water loss, such as a dropping water level, wet spots in the pool area, or the sound of running water. If you suspect a leak, contact a professional pool repair service to locate and repair the leak promptly.


Maintaining a clean and well-functioning pool requires regular attention and care to prevent and address common pool problems. By staying proactive in testing and balancing your pool water, ensuring proper filtration and circulation, and addressing issues such as algae infestation, pH imbalance, chlorine deficiency, calcium buildup, clogged filters, and leaks promptly, you can keep your pool in top condition for swimming season after season. With proper maintenance and care, you can enjoy a clear, clean, and refreshing pool that provides endless enjoyment for you, your family, and your friends.
