Cloudy water in my pool: A comprehensive guide for crystal clear pool water

Maintaining a pool may appear complex, but with the right tools and a suitable routine, you can avoid cloudy water and instead enjoy crystal-clear water all year round. This comprehensive guide will support you step by step with your pool maintenance, by integrating the Hayward brand's innovative solutions to simplify this task, to deal with cloudy water and obtain perfectly clear water.

Why does the water in a pool become cloudy?

Maintaining crystal-clear water in your pool is key to fully enjoying swimming in it. However, cloudy water can quickly spoil your experience. Here we explain two frequent causes and how to remedy them.

Imbalance of chlorine rates

Chlorine is a key element for disinfecting the water in your pool. However, imbalances in the levels can make the water cloudy.

Under-chlorination

If the chlorine level is too low, the water will not be sufficiently disinfected, which enables bacteria and micro-organisms to proliferate. This can lead to cloudy or milky water.

Over-chlorination

Inversely, excess chlorine can cause chemical reactions, in particular with the organic matter present in the water, which can also cause the water to become cloudy.

The solution is to regularly use a chlorine tester to ensure that the level stays between 1 and 3 mg/l. Adapt the dosage based on the results obtained and the outdoor conditions (temperature, number of bathers using the pool).

Presence of algae

Algae is another frequent cause of cloudy water.

Green algae

These micro-organisms develop rapidly if the water treatment is not sufficient. They cause a green tint and can make the pool floor slippery.

Black algae

More resistant, these form dark patches on the walls or floor of the pool and require more intensive treatment.

The solution: maintain a suitable level of disinfectant and check the pH (between 7.2 and 7.6). If algae appears, use a suitable algaecide and brush the affected areas.

By quickly identifying the causes of cloudy water and implementing the appropriate measures, you can regain crystal-clear water in no time. Don't forger to regularly check your filtration equipment and treat your pool preventively to avoid these unpleasant issues.

How do I maintain crystal-clear pool water all year round?

Filtration: the key to maintenance

Why this is important: filtration is essential for maintaining clean, clear water. It eliminates impurities, debris and micro-organisms from the water.

Hayward's advice: select a high-performance filtration system such as Hayward's SwimClear™ cartridge filter. This innovative system is designed to offer fine filtration, capturing the smallest particles and guaranteeing clear water. SwimClear™ filters twice as effectively as a sand filter and has a higher retention capacity.

Balance and cleanliness of the pool water

Why this is important: balanced water is crucial for the safety of bathers and the durability of the equipment. The pH, chlorine level and alkalinity must be regularly monitored.

Hayward's advice: the new range of automatic dosing pumps, such as the Easy Chem and Pro Chem models, continuously analyse the water quality and adjust the dosing of products required for optimal disinfection. These systems offer exceptional reliability and programmable alarms for better security, guaranteeing you peace of mind all year round.

Cleaning: keep the pool clean

Why this is important: debris and dirt can accumulate rapidly, making the water cloudy and susceptible to the proliferation of algae. 

Hayward's advice: invest in a Hayward pool cleaner, such as the TigerShark® model. These cleaners are designed to clean the pool floor, walls and waterline effectively, helping you gain precious time.

Water circulation: avoid stagnant zones

Why this is important: good water circulation prevents the formation of stagnant areas where the algae and bacteria can develop.

Hayward's advice: Hayward's TriStar® VSTD variable-speed pump is ideal for this. It allows the flow rate to be adjusted to the specific requirements of your pool, guaranteeing optimal circulation whilst saving energy, which helps you maintain perfectly healthy, clear water.

Protection of the pool: preserving the water quality

Why this is important: protecting your pool from outdoor elements such as dust, leaves and insects contributes to maintaining clean, clear water.

Hayward's advice: use a suitable pool cover and consider installing a Hayward heat pump to extend the bathing season with a water at a pleasant temperature.

Regular tests: monitoring of the water quality

Why this is important: by regularly testing the water in your pool, you can rapidly detect any imbalances and correct them before problems arise.

Hayward's advice: use complete test kits to perform a rapid, precise analysis of the water parameters.

Winterising: preparing your pool for the winter

Why this is important: winterising protects your pool from the damage caused by ice and makes it easier to reopen the pool in the spring.

Hayward's advice: for effective winterising, begin by careflly cleaning your pool and adjusting the water parameters. Use winterising floats to avoid ice damage to the walls and pipes. In addition, Hayward's TriStar® VSTD variable-speed pump can be used to circulate the water optimally, even in low consumption mode, which ensures that your pool remains in good condition throughout the cold season. Also conside covering your pool with a suitable cover to protect it from debris and bad weather.
