Spread the love

Most people have experienced colored pool water at one time or another. While discoloration can occur for a variety of reasons, it is usually a sign of poor water quality. However, the color of the water can vary from light to dark green, and the reasons for this are not always obvious.

If you are not sure what causes your pool water to turn green, read on. We will discuss several common factors that contribute to the pool water becoming discolored, as well as give you some tips on how to prevent the incident from happening again.

Improper Maintenance

Anytime you have a pool, there is the possibility of it getting contaminated with algae. While most homeowners care for their pools by cleaning it with a pool cleaner once or twice a week, keeping the water clean by itself is not enough to prevent algae growth. Instead, you need to make sure that the pool is clean at all times, and that it is properly maintained on a regular basis.

The main reason behind this is that algae needs sunlight to grow, and in order to ensure that it gets the necessary light, you have to keep the pool water clean. If you are not sure how to properly maintain a pool, then speak to your local pool store about getting an expert to come and give you a demonstration or two. They will be able to walk you through the steps involved in keeping a pool clean, as well as answer any questions you might have about the subject.

Overuse Of Chlorine

If you are a regular user of chlorine in your pool, then you are doing your pool a favor by keeping it clean. However, you have to be careful not to go overboard and introduce too much chlorine into the pool. Just a one-time addition of chlorine every week or every other week should suffice, and you should not have to add additional chemicals to the pool to keep it clean. Adding too much chlorine can cause damage to your pool, including discoloration and the proliferation of algae.

When you are using chemicals for cleaning and prevention purposes, it is always a good idea to test the water on a regular basis for pH levels and contamination. If you know that your pool water is usually at a 7.4 pH level, then you should not be afraid to add some acid to it. This will cause the color to lighten up immediately.

Leaky Faucets And Showerheads

Most importantly, make sure to fix all the faucets and showerheads in your house that are leaking. Faucets and showerheads that are not waterproofed can cause water damage, and if you notice that there is water damage occurring in the attic or basement of your home, then it’s time to fix the problem. This will help prevent mold and mildew growth in the future.

If a faucet or showerhead is not waterproofed properly, then it will inevitably start dripping during heavy rains or after a hard day of swimming. Instead of having a puddle on the floor or the faucet, respectively, you would notice that the floor is gradually becoming wet. Mold and mildew can grow easily in areas where there is constant moisture, so if you want to prevent this from happening, then fix all the faucets and showerheads that are leaking. It’s also a good idea to check for signs of wildlife in and around your pool area, as they can also cause damage if not controlled properly.

Overuse Of Sunlight

Last but not least, make sure to prevent algae growth by limiting the amount of sunlight that is getting into the pool area. You can easily do this by keeping the windows closed during the day, as well as removing any pool lights that are not protected from the outside environment. For best results, cover the pool completely with a tarp during the day, and remove it only when necessary (such as on warm days or when the sun is directly overhead).

Algae growth is the number one cause of pool water discoloration, but it is also one of the most preventable. Just a few measures can be taken to keep your pool clean and its water bright. Proper maintenance, as discussed previously, is an essential part of this, as well as regular testing for pH levels and water clarity. There are also chemicals that can be used to kill algae, but these should only be used by professional pool cleaners, as they can be dangerous if handled incorrectly.

In conclusion, it is essential to remember that the color of your pool water can vary from light to dark green, and that this discoloration is usually the result of water contamination. However, it is usually preventable by following a simple set of guidelines. Just remember to test the water regularly for clarity and pH levels, and get a hold of your local pool store if you are not sure how to maintain a pool. In addition, make sure to fix all the leaks in your faucets and showerheads, as well as close all the windows and turn off the interior lights whenever you leave the house. Last but not least, make sure to limit the amount of sunlight that is getting into your pool area by keeping the windows closed and removing any pool lights that are not protected from the outside environment. In this way, you will be able to keep your pool clean and its water healthy and vibrant for many years to come.
