Problems with your pool water

The pool water is often prone to issues like green or cloudy water, excessive eye or skin irritation while swimming, or unusually high chemical usage. The issues can be sorted out by taking adequate measures and care. Always remember to test your water for pH and other chemical levels. A good diagnosis is effective in taking care of your pool and the pool water. With a proper diagnosis, managing your pool water is much easier. Let’s learn about some problems faced by your pool water.

Cloudy Pool Water

The pool water can turn cloudy or milky due to various factors. Cloudy pool water can be formed due to improper levels of chlorine, imbalanced pH and alkalinity, very high Calcium Hardness(CH) levels, faulty or clogged filter, early stages of algae, ammonia, and presence of debris in the pool water. The cloudiness can be eradicated by balancing the pH levels of your pool water, shocking your pool, eliminating ammonia, getting rid of young algae, balancing the chlorine levels, correcting the calcium hardness, backwashing the filter, removing debris and by scrubbing and vacuuming the pool.


Sometimes, we can find white lines or substances on the pool walls. This is called as the scaling of the pool. Scaling of the pool is caused primarily due to high calcium hardness of the pool water. Other reasons for scaling are very high levels of pH and alkalinity. Scaling can be reduced by adding pH minus or muriatic acid to lower the pH levels or by adding a sequestering agent to reduce scaling.

High Chlorine Levels

The ideal range for pH value of the pool water is 7.2-7.8. The pH value can go higher than expected. This may occur due to unstabilized pool water, presence of debris in the pool skimmer and due to high phosphate levels of the pool water. This can be controlled by adding a stabilizer, cleaning the skimmer basket and the filter and by adding a phosphate remover. Constant testing of the pH levels and alkalinity is recommended.

Eye or Skin Irritation

Sometimes, when we take a dip in the pool, we face some itchiness or irritation on our eyes or our skin. This is due to a few factors like a high amount of combined chlorine or as the pH levels go out of balance. the ideal way to treat the pool water is by shocking the pool. We also need to ensure that the pH value is always in the ideal range of 7.2-7.8.

Metal Corrosion

The metal components of the pool can be prone to corrosion due to low pH levels, which indicates the acidic nature. To avoid corrosion of the metal components of the pool, we need to stabilize the pH levels of the pool water to the ideal level, which is 7.2-7.8.

Staining or Coloured Water

Sometimes, we may notice the change in the colour of the water. The pool water might appear to be stained or maybe a bit off-coloured. This is due to the high concentration of metal particles in the water. Adding a sequestering agent can help to remove these concentrations and restore clear pool water.

Growth of Algae

Algae are microorganisms that may be present in the water. The algae growth can cause discolouration of water and even serious health hazards. The unchecked growth of algae is due to low levels of chlorine in the pool water. The best way to get rid of algae is by shocking the pool with a super chlorinator. If there are any black algae spots on the walls of the pool, brush it off regularly.

It’s advised to test your pool water regularly. Testing the water helps in getting an early diagnosis of the pool water and making the perfect pool chemistry before the water turns problematic. Keep your pool water clean and enjoy your perfect dip.
