Did you know the pool water’s apparent color can change with time and sunlight? Let’s explore how!
The Appearance Of Pool Water Is Time Sensitive
Looking at your pool water from above, you might think its appearance is set. You get in, swim a few laps, and then head inside to relax. But, as you know, appearances can be deceiving. Let’s take a look at how sunlight, time, and mineral content affect the look of your pool water.
How Does Time Affect Pool Water?
Time is one of the three main factors that determine the appearance of your pool water. Here’s how it does so.
- Light exposure
Let’s discuss each one.
- Light Exposure
As sunlight passes through the water, it heats it up. The sun’s ultraviolet rays are also responsible for oxidizing chemicals in the pool water. These oxidized chemicals, commonly known as “radicals”, contribute to the water’s taste and smell.
Oxidation is the process of taking electrons from molecules to form molecules with less electrons. For instance, chlorine is often used in pools to oxidize the water’s compounds. When chlorine molecules are oxidized, they form smaller, less stable molecules that are less harmful to the environment. This is why the pool water often has a foul taste and odor when it’s first turned on. This is why it’s important to keep the pool clean at all times.
Why Does Temperature Affect Pool Water?
This factor also refers to the temperature of your pool water. As your pool water gets cooler, its molecules slow down and a sort of gelatinous consistency takes over. This is why as the seasons change and the temperature drops, your pool water turns opaque and murky. It becomes less appetizing for both humans and fish.
Molecules are usually depicted as little balls that are constantly in motion. When water gets cold, it becomes more like a rigid solid. So when you drop your swimming pool water’s temperature below 72 degrees Fahrenheit, it changes from a liquid to a solid. This is why it’s important to keep your pool at a constant temperature above 72 degrees Fahrenheit. This will keep your pool’s pH balance in check and reduce health problems for you and your family.
- Light Exposure
Time and sunlight are not the only factors that influence the appearance of your pool water. There’s also the mineral content of the water itself. Did you know that dissolved minerals can affect the transparency of your pool water? This happens when certain minerals interfere with the absorption of light by other molecules in the water. In other words, dissolved minerals can cause the pool water to become more or less opaque.
Why Does The Mineral Content Of Pool Water Have An Effect?
Any type of ionic pollution, such as heavy metals or radiated water, has the potential to change the transparency of your pool water. These ions interfere with the normal functioning of cells in water-dwelling organisms. Did you know that certain dissolved minerals can alter the UV reflectance (transparency) of water?
In other words, certain minerals can cause the water to either absorb or reflect more ultraviolet (UV) radiation than usual. When this occurs, the pool water begins to take on a unique appearance similar to that of glass. This is because certain minerals are responsible for changing the material property of water. In other words, dissolved minerals can cause the water to change from a liquid to a solid (i.e., ice). This unique appearance is often referred to as “glass clear.””
Do You See The Connection?
Did you notice that all three factors discussed here are interconnected? This is because they all affect each other. The amount of time it takes for sunlight to pass through the pool water is based on the temperature of the water and the type of light exposure.
Let’s look at this example. Say your pool water is 10 degrees Fahrenheit. This means that it will take 10 minutes for sunlight to heat it up to the right temperature for you to swim comfortably. So let’s say you’re an average human and don’t want to stay in the water for more than 10 minutes. This is when you head inside to dry off and warm up. As you enter the house, you feel like you’re walking into an oven.
Does this sound familiar?
Even though you can’t see it, something is changing about the way your pool water looks. It’s being altered by sunlight, time, and temperature in order to make it appear as it does. But that’s not all there is to it. The truth is, the appearance of your pool water is actually very changeable. This is because all three factors discussed here influence each other in a constantly shifting dynamic. This means there’s always something new to learn about your pool water.
Did you know that the water in your pool does not need to be purified any more than the air does? Did you know that dirt and debris collecting at the bottom of the pool can clog your filter and make your pool water less transparent? Did you know that the presence of certain chemicals such as chlorine and lead can also harm you and your family?
Now you do! It’s easy to understand why keeping your pool clean is so essential. Swimming in dirty water is not only unhealthy but also unpleasant. This is why if you keep seeing strange particles floating around in your pool or notice any strange colors, it’s time to change them. You can’t see these particles because they’re too small, but they’re there all the same. These are things you need to get rid of before they become a problem. The sooner you do this, the better your overall swimming experience will be.
Remember: there’s no such thing as ‘perfect’ pool water. Always keep working at improving the quality of the water in your pool!
