If you are always wondering why the water in your swimming pool always turns green, you are not alone. Some homeowners just call for professionals to clean it without really knowing the cause of green pool water. If you are curious why this happens, you will get your answers here. So before you learn how to clean a green swimming pool, here’s why you are dealing with this problem.
Lack of Chlorine
One known reason why pool water goes green is because of the lack of chlorine. Remember that the chlorine prevents the algae from growing. So if the water does not have enough chlorine, the algae can grow quickly to the point that the entire pool will turn green even just for a day. And when you have an outdoor pool, the warmer water makes the alga grow faster.
Pollen
Another reason is when you have nearby plants and trees. The pollen carried to the pool water by the wind is too small for the standard filter to remove. More pollen will build-up throughout the entire year and it will settle on the liner. If you continue to let this happen, the buildup will be too thick that it will turn all the water green.
Metals
This is also one reason why pool water turns green. Usually, copper is the culprit from the heater elements of your pool. When you shock the pool and the water has metals in it, this will oxidize. If the metal levels are too high, they can turn green after they oxidize.
A clean and clear swimming pool water is the safest to use. Now that you know why your water turns green, it will become more convenient for you to find ways to avoid it from happening. And also, knowing how to determine the cause of the problem will make it easier for you to treat the issue sooner.
