Why is my pool cloudy after rain?

4 min read

Asked by: Roseanna Harris

Rain does trap pollutants in the air, but unfortunately, it doesn’t make them disappear. Instead, the rain brings the pollutants from the air down onto the ground. What this means for your pool is that all the contaminants and pollution that were in the air are now floating in your pool water, making it cloudy.

How do you clear up a cloudy pool after rain?

Cleaning a Swimming Pool After Heavy Rain

  1. Skim the pool to remove excess debris.

How long does it take for a cloudy pool to clear? Depending on how cloudy your water is, it may take 2-3 days for your water to clear.

Why is my pool cloudy after a heavy rain?

Environmental reasons like bird droppings, flower pollen and run-off. The chemistry of your pool water, including chlorination, pH and alkalinity levels. Inadequate circulation caused by blocked skimmer boxes. Dirty or damaged filtration equipment that needs repairing or replacing.

Is it OK to swim in a cloudy pool?

You shouldn’t swim in a cloudy pool for several reasons: If you can’t see the bottom of the pool, struggling swimmers will also be hard to spot, making the risk of drowning much higher. Cloudy pools are full of bacteria and pathogens that can cause urinary tract infections, stomach problems, and eye irritation.

Does rainwater affect pool water?

Rainfall dilutes pool chemistry levels and lowers the readings for pH, alkalinity, hardness, stabilizer, and chlorine. Rainfall does not contain chlorine. As well, rainfall brings with it small amounts of contaminants that are washed into the pool.

Can too much chlorine cause cloudy water?

Excessive levels of pool chemicals can cause your water to become cloudy. High pH, high alkalinity, high chlorine or other sanitisers, and high calcium hardness are all common culprits.

Does shock clear a cloudy pool?

Poor water chemistry causes most cases of cloudy pool water. Test your water to make sure it’s properly balanced. Chlorine issues often cause hazy-looking water. Adding a recommended dose of pool shock to your pool can clear it right up.

Will baking soda clear a cloudy pool?

Baking soda can work wonders in a pool. Baking soda can: Help to clear cloudy water and restore the sparkle. Spot-treat algae.

Is pool clarifier the same as shock?

It’s not a good idea to use pool shock at the same time as clarifier. Some clarifiers are polymer based and the shock can act to break up the polymer causing the clarifier to be ineffective. It’s best to shock your pool before and wait a day or two before adding clarifier.

Will low pH cause cloudy water?

If the pH is too low, less than 7.0, the water is too acidic. Having a low pH can cause damage to the lining of the pool, causing it to wear away. Debris and particles from the corroding lining can cloud the pool’s water.

Does high pH make pool cloudy?

High pH, high alkalinity, and calcium levels above 400 ppm can cause cloudy pool water. The high pH can also make your chlorine sanitizer less effective.

Will low chlorine cause cloudy water?

For instance, when levels of chlorine or bromine are too low, the concentration of these chemicals may not be sufficient to kill algae spores and could result in algae blooms and cloudy pool water.

How do you clear up a cloudy pool in 24 hours?


And ran the pump on recirculate for two hours and then shut it off over the night and this is the results. It's. So much clearer than it used to be now I just have to vacuum it all up.

How can I make my pool water clear naturally?

Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity.
