Everyone needs water, we all grow crops water, we drink water, and our pets need water too. But what is the difference between fresh and saltwater? In this article, we will discuss the differences between freshwater and saltwater, how to tell which is which, and what you should do if you suspect your pool water might be saltwater.

What Is Freshwater?

If you’ve ever taken a look at a map of the world, you’ll probably notice something interesting: most of the earth is covered in water. Some parts of the world, like the Arctic Circle or the Antarctic Circle, are almost completely free of water because of the extreme cold or warmth of the climates there. But for the most part, the entire planet is covered in water, with a small portion located in polar regions like the Arctic Circle and the Antarctic Circle. It should come as no surprise that most of the world is covered in water, because the most common form of life there is water based. We’re surrounded by water, from the tiniest microbes, to fish, to shrimp, to humans. In fact, if you zoom out far enough, you’ll even see the Earth is mostly made of water. It’s the only element that makes up more than 90% of the planet. So it’s quite natural that most of us are concerned with keeping our pool clean and healthy.

Freshwater is any water that is free of sewage pollution and impurities. It is most commonly found in oceans, lakes, and rivers. Water that is relatively clean flows from glaciers, melting snow, and rainwater, as well as springs and aquifers. This is what is known as “greywater” – water that has not been cleaned or purified enough to drink. For example, tap water and bottled waters are both considered fresh water sources, as they haven’t been treated or cleaned with chemicals in order to remove toxins or impurities. On the other hand, ocean water and untreated well water are both considered saltwater sources, as they typically contain a high amount of minerals and salt.

What Is Saltwater?

If you’ve ever visited the coast, you might have noticed something interesting about the water. Instead of being clear and fresh, the water near or on the coast is typically quite cloudy and milky white. This is caused by high concentrations of minerals and salt in the water. Saltwater is any water that contains a high concentration of minerals and salts. These elements form shells or rocks that are deposited on the ocean floor when the water is slowly seeped down through the earth’s crust. There are a few different minerals and salts that contribute to the white color of the water. These elements include magnesium, calcium, aluminum, and potassium. The most common salt around the world is sodium chloride (commonly known as table salt or saltwater), so much so that it is used as a primary component in the industrial production of paper, cement, and aluminum. The high concentration of these elements in the water causes it to be undrinkable by most people, and even more so if it is brackish or highly salty. This makes it quite dangerous to life – very hard for most aquatic animals to survive in such an environment.

Signs Of Saltwater

Though we usually think of saltwater when referring to the ocean, it can also be found in smaller bodies of water such as lakes and ponds. The biggest difference between these and the ocean is that smaller bodies of water tend to evaporate quickly, meaning saltwater can be transported great distances from its source. For example, much of the East Coast of the U.S. is actually located over an old saltwater formation that was deposited hundreds of millions of years ago. This is because saltwater can more easily seep through loose soil and rock, leading to larger pools of water that can then evaporate. Saltwater is quite mobile, and can quickly be carried away by wind or water currents. For these reasons, it is quite easy for us to become completely desalinated, or stripped of salt, through the accumulation of high levels of rain or the melting of snow. When this happens, the water becomes quite unusable and can even be harmful to an organism’s health. The easiest way to tell if the water in your pool is fresh or saltwater is to check the chemical make-up of the water. If it has a pH of 7.0 or more, then the water is fresh and can be used without any problems. However, if the pH is less than 7.0, then the water is likely saltwater. You should consult with your local pool owner or manager to receive clarification on this matter.

One of the biggest problems with saltwater is its corrosiveness. Due to the high concentration of minerals and salts, the water has a very high acidity – around pH 2.0 to 4.0. The minerals in the water actually contribute to its acidity. For example, when calcium encounters water, it becomes hydrocalcium, which is simply calcium surrounded by hydrogen atoms. These hydrogen atoms are highly reactive, and contribute to the acidity of the water. This is why the minerals in the water are commonly known as “acids”, “hydroacids”, or “acida”. The higher the concentration of these elements, the more acidic the water becomes. Simply put, calcium turns any body of water into a powerful acid. This is why most pools should be located away from the coast, where there is no threat of seawater intrusion. However, this is not always possible, and even when it is, it increases the chance of environmental damage from pollution. This is why it is best to keep the minerals in your pool at a minimum or nonexistent, and only add them when absolutely necessary.

Protecting Your Pools’ Water

To protect your pool’s water from becoming too salty or polluted, there are a few things you can do. For one, make sure the water is fully replenished at least once a day. This prevents the buildup of minerals and salts that can cause serious damage to your pool’s ecosystem and health. It also prevents the water from becoming more acidic, as the minerals dissolve and the water is subsequently mixed from different sources. Evaporation is also a significant factor in the desalination of saltwater, so it is important to protect your pool from being located near or on the coast. Fortunately, there are a variety of ways this can be done. For example, if you live in Florida, there are several springs located around the state that provide freshwater for swimming pools and other uses. Some of these are even available for commercial use. The best option would be to find a way to filter the water and remove the minerals and salts. This is better for the environment and ensures the water stays fresh for aquatic life.

What Do You Do If Your Pool Water Is Saltwater?

If your pool water is saltwater, then there are a few things you need to do. First, stop adding more water to the pool. This will cause the water to become more concentrated, and eventually lead to the organisms living in the pool being harmed. Take the time to allow the water to settle down and make itself evident above the surface. Next, remove the oxygen from the water by placing it into an oxygen-free container. An easy way to do this is to tie a brick to the end of a string and drop it in the pool. The oxygen in the air will eventually dissolve into the water, causing the demise of most of the living creatures in your pool. After this, you can begin adding more water to the pool at a controlled rate. Though this may seem like an unnecessary step, it is best to ensure minimal contact between the saltwater and the organisms that live in the pool.

Now that you’re aware of the differences between freshwater and saltwater, you can be sure that your pool’s water is fresh and healthy, and add more safely and effectively. Remember, the pH of the water is crucial, as it directly relates to its acidity and the damage that can be caused from too much or too little salt. With a little bit of knowledge, you can ensure the safety of your pool’s water and the well-being of all the creatures that live in it.
