How can I prevent or fix my cloudy pool?
When we think of the ideal swimming pool, we conjure up images of cool, clean water - deep blues and clear reflections. A pool is a luxury fixture in your home that cannot be ignored for weeks on end, and then expect it to be in good condition whenever you are ready to swim. It requires regular servicing to keep it healthy and safe. If you overlook servicing the pool, you will be rewarded with the most undesirable of all things; cloudy pool water.
But what makes a pool cloudy? If this happens, how do you go about bringing back the clear blue finish?
What is cloudy pool water?
Cloudy pool water is often a result of one or a mix of things, including a chemical imbalance, poor filtration or an influx of skin, dust and dirt particles. However, environmental factors might also have a part to play depending on your location. Regardless of the cause, cloudy pool water is notable for its milky and murky appearance, which it gets from tiny particles reflected by the sun.
While you can comfortably skim leaves and other debris from the water, these particles are too small to see, let alone scoop up. These particles will leave your pool looking either dull, hazy, cloudy or opaque if it has gotten out of control.
Why is my pool cloudy?
Filtration: The vast majority of cloudy pool water problems are linked to poor quality filtration, which is often caused by clogged filters or a pump that needs replacing.
Chemical imbalance: An imbalance of chlorine and pH levels will result in a layer of chloramine which can give off that classic cloudy appearance. High pH levels can be caused by anything from too much alkalinity and calcium hardness. The former should be no higher than 200ppm and the latter should be no higher than 400ppm. It can be a difficult balance to maintain, of course, which is why you will want to have your pool serviced regularly by a professional.
Particles in the water: There is a good reason that we are advised to shower before swimming – the particles on our bodies can play havoc with the pool water. Sweat, natural body oils and skin particles all contribute to the problem, but the worst offender is sun lotion.
Environmental hazards: If the water circulation is not operating at optimal levels, then tiny debris such as pollen and dust can build up in the filter. Even rainwater can affect the pool water, leading to cloudiness, as it not only breaks down pool chemicals into nitrates and phosphates but will dilute the chlorine levels too.
How can I prevent or fix my cloudy pool?
Mandatory showers: Always shower before getting into the pool and ensure your guests do likewise.
Keep the pool clean and covered: The first step in any de-clouding job should always be a thorough clean, including skimming the debris from the surface and scrubbing and vacuuming the sides and bottom. You might also need to shock the pool if it’s developed algae.
Keep your filter running: The filter should ideally be running around 10 hours a day, even if the pool is not in use that often. Ideally, you should run the filter continuously, but we understand this may not always be practical.
Get professional help: Maintaining a pool involves commitment and time. If you do not understand what you are doing, you could be harming more than helping. Sure, you can clean the filter and check the chemicals, but how will you know if the filter is working correctly and how to keep the water chemistry balance in check?
