Why Is My Pool Water Cloudy After Rain? [Fact Checked!]

Spread the love

Getting wet is no fun if the water is not clear and clean. After a long, hot summer, an unexpected downpour can ruin your swimsuit plans. Even if you are fully clothed, getting wet and cold is still no fun. With this in mind, here are just a few reasons why your pool water might be turning cloudy after a light rain. Hopefully, this will help guide you in choosing the proper course of action.

Overwhelmed By Downpours

Whether you have a pool at home or in the town, if it is a public pool, it will be prone to being overwhelmed by downpours. Even if you live in a place where it rarely rains, there is always the possibility that it could rain at any time. This makes it essential to be weather-proof through proper pool cover installation.

While a few heavy downpours would not hurt your pool, constant light drizzles could turn your clear blue water opaque.

If you notice, cloudy pools are more common in the South because of the constant humidity. When it rains in the North, the water tends to stay clear because of the low humidity levels. You should not be fooled by this, as rain is still water and can cause all kinds of problems if it manages to infiltrate your pool area. This is why you should always be on the lookout for signs of leaks and other damage, which would inevitably lead to serious illnesses. The Centers for Disease Control and Prevention (CDC) report that exposure to contaminated water can lead to rashes, skin irritations, and even liver damage. The water in your pool could become contaminated with various chemicals such as chlorine, algae growth hormones, and heavy metals. The most common source of this water damage is storm sewers that overflow during heavy rainfalls. This water can then find its way into your pool via surface runoff.

Chlorine

Chlorine is an element that is a byproduct of water damage and electricity. It is a common cause of pool water discoloration, particularly in areas where the water source is chlorinated. This is one reason why chlorinated pools have a yellowish tint to them. If you suspect your pool water is getting a bit murky, you should check for signs of chlorine poisoning. Your pool will appear to be clear and sparkling when viewed from above, but upon closer inspection, there will be a dull hue to the water. The chlorine in your pool will strip the nutrients from your fish, leaving them vulnerable to diseases.

Algae

Algae is one of the most common causes of pool water discoloration. This type of water pollution stems from excessive fertilizer use in the surrounding area. Certain types of algae, such as cyanobacteria, produce toxins that can harm humans and animals. In high enough amounts, these toxins can be fatal. The most common symptoms of excessive algae growth include rashes, skin irritations, and even liver damage. The presence of algae in your pool will cause its water to turn an opaque green color. If you are unsure whether or not your pool is affected, you should contact a professional water quality tester. Some homeowners have found that using specific types of bleach or hydrogen peroxide has helped rid their pool of algae.

Tropical Fish

Tropical fish are another major factor that contributes to pool water discoloration. Typically, they are brightly colored and will impart a brilliant shine to your pool. Unfortunately, these bright colors hide the fact that tropical fish can become diseased easily. The most common symptom of a sick or injured tropical fish is a dull appearance. They may also appear sluggish and have difficulty swimming. These symptoms should not be confused with those of a nice, plump fish. If you want to keep your pool clean and clear of tropical fish, consider using special barriers or nets to prevent them from swimming in and out. You should also regularly clean the water with a pool vacuum to remove any dead fish or other aquatic creatures.

Filtration System

If you use chlorine as your pool’s main disinfectant, you should consider investing in one of the many different types of filtration systems that are on the market. Without proper filtration, your pool water will become contaminated with various impurities. The most common sources of these impurities are cigarette butts, paper towels, and other solid wastes that are flushed down the toilet. If you do not have toilet paper or other similar products stored elsewhere, they will eventually find their way into your pool via surface runoff or drainage pipes. Studies have shown that properly filtered pool water can prevent various types of illnesses, including liver disorders, asthma, and rhinitis. Filtration is essential if you want to maintain a healthy pool environment and prevent any unpleasant surprises from happening. This is why we recommend using an automatic pool cleaner with a water purifier along with it.

Dissolved Gasses

Dissolved gases are another common source of pool water pollution. These are gases that are dissolved in the water. The most common dissolved gas found in water is carbon dioxide. It occurs naturally in the atmosphere and is a byproduct of plant life. When animals, such as humans, consume plant matter, they break it down. This process releases a lot of carbon dioxide into the atmosphere. If you have a pool that is directly connected to the atmosphere, you should consider installing a gas vacuum line to remove this dissolved gas.

Carbon dioxide is sometimes referred to as the “plant equivalent of fossil fuels” because it is a product of human activity as well. It is a greenhouse gas and has been implicated in global warming. Although it is not currently detectable in most water supplies, it is highly concentrated in areas where natural gas is found in abundance or has been used for energy production. If you suspect that your pool water might be contaminated by this gas, you should contact a professional water tester to have them analyze your pool. They will use sophisticated equipment to detect even the slightest amounts of this gas. If they do find any, you will need to have your pool professionally cleaned. Fortunately, there are ways for you to prevent this type of pollution from occurring in the first place.

Improper pH Levels

The pH of your pool water is another important factor to consider. The pH level of your pool determines how acidic or basic the water is. There are many different types of pH meters that you can purchase to test the pH levels of various liquids, such as water. If you want to keep the pH levels of your pool water in a healthy range, it is a good idea to test it regularly and make sure that the proper chemicals are being used.

Temperature

The temperature of your pool water is another important factor to consider. The water that is too hot or cold can cause serious problems for your pool and its inhabitants. Your pool will not be able to sustain a healthy population of fish if the water is too hot or cold. If you notice, many types of fish are best kept at a constant room temperature. This is why most public pools are kept at a constant temperature of about 77 degrees Fahrenheit. This is also why most home pools are equipped with a heater, which is run by either electric current or hot water.

Nutrients

Nutrients are substances, such as calcium or magnesium, that are necessary for plant and animal life. Certain nutrients are necessary in smaller quantities than others, such as oxygen and hydrogen. Nitrates, phosphates, and sulfates are usually present in larger quantities and are generally less harmful. The opposite is true for heavy metals, such as lead and mercury. Excessive quantities of these metals can lead to serious health problems.

Summary

Getting wet is no fun if the water is not clear and clean. After a long, hot summer, an unexpected downpour can ruin your swimsuit plans. Even if you are fully clothed, getting wet and cold is still no fun. With this in mind, here are just a few reasons why your pool water might be turning cloudy after a light rain. Hopefully, this will help guide you in choosing the proper course of action.
