An imbalanced pool, poor pool filtration, an abundance of unwanted particles, or environmental factors are frequently to blame for pool water getting cloudy. Cloudy pool water can occur for a variety of reasons, including:
- Pool filtration: If your pool filter fails, your pool will get hazy and dirty as the water becomes stagnant.
- Improper chlorine or pH levels: When the pH levels are out of equilibrium, the free chlorine becomes ineffective and the levels fall. When there is insufficient free chlorine, chloramine occurs, and it is this mixed chlorine that causes the hazy appearance of your pool. A water pH beyond its typical range will also render chlorine ineffective in killing bacteria and other natural organisms, lowering the water’s quality and risking algal overgrowth.
- Too much total alkalinity: pool water with a high alkalinity is frequently cloudy. This is due to the fact that it might produce a pH imbalance and calcium scaling.
- Calcium hardness is too high: Calcium levels in water are unstable and will be influenced if there is a pH or total alkalinity imbalance. Temperature determines the ideal calcium hardness range of 100–400 ppm. When the calcium hardness exceeds 400 ppm, persistent cloudiness and calcium scaling are common.
- Environmental debris: Environmental debris, such as leaves, twigs, and flowers, can have an impact on the water quality of your pool, especially if your pool’s circulation is excellent. Pollen, dust, and bird droppings, for example, have a negative impact on the appearance of your filter and can accumulate in it.
- Rainwater: If you’ve recently had a heavy storm and your pool is cloudy, this is most likely the source. Cloudy pool water after rain might also decrease your chlorine levels.
How do you clear up a cloudy pool?
How to clear cloudy pool water? Below are some of the ways for clearing cloudy pool :
- Keep an eye on the pH level and the total alkalinity: The pH level of the pool water has an effect on how all of the other chemicals, including chlorine, work. As a result, you should regularly check the total alkalinity and pH level of your pool to ensure that they are neither excessively high or low.
- Ensure that the filtration and circulation systems of the pool are clean: A subpar system for water circulation can also be a significant issue. If the water in your system is unable to move around freely, it will become hazy and stagnant. To fix cloudy pool water, check that the pump you are using is the appropriate size, that the filtration system is operating for the recommended amount of time, and that the DE and cartridge filters are cleaned, backwashed, or replaced on a regular basis.
- Eliminate the particles that aren’t wanted: the surroundings and the weather could also be to blame for the hazy water. When the cloudiness does not go away, you can remove the debris from the water and make it clearer by using a pool net or a clarifier.
