How to Remove and Keep Pollen Out of Your Pool


Springtime is a beautiful season, but for those with allergies, it can also be a time of misery. One way to get relief from the pollen is to take a dip in the pool. However, if your pool is full of pollen, it can actually make your allergies worse. 

Not only does pollen make the pool water look dirty, but it can also clog filters and reduce circulation. Do not ever dive into a pool contaminated with pollen. The pollen in your pool will not stand a chance against your filter, your skimmer, and you. 


Why is my pool full of pollen?

Why is there pollen in my pool

If you’ve ever opened your pool to find it filled with a yellow powder, you’re not alone. Each year, huge amounts of pollen are released into the air, and some of it ends up in swimming pools. But why does pollen accumulate in pools, and what can be done about it?

Pollen is light and dry, so it easily floats on the surface of water. When wind blows pollen grains into the pool, they float around until they eventually settle at the bottom. In addition, pollen is attracted to chlorinated water, so it often accumulates near the edges of swimming pools.

Pollen comes from your garden plants and from your neighboring gardens and even from gardens miles away. 

Is it Really Pollen?

You may have a problem with pollen if you notice some floating on the top of your pool. However, it is likely that the pool has already collected the material and it may be algae instead.

Algae will stick to the edges and bottom of your pool, making it difficult for you to filter with the pool’s filtration system.

Pollen in your swimming pool, on the other hand, might appear like yellow algae or mustard algae, but float on the surface.

Before you start cleaning, make sure that you are dealing with the pollen. It is the way that it collects that makes the difference.


How to Remove Pollen from your Pool

It is easy to eliminate it, but keep it at bay, you’ll have to be vigilant. 

1. Filter

Your pool filter probably doesn’t need to be running 24/7, seven days a week. The filtration system can be your best defense against pollen. Although it won’t completely eliminate it, it is a good place to begin.

It will at the minimum reduce the manual labor required to remove the pollen. Although it may cause some increase in your energy costs, it is worth it to have less pollen to collect yourself.


2. Skimmer

To collect any pollen that may have accumulated on the surface overnight, use a fine-mesh skimmer every morning. This may be repeated several times a day during heavy pollen seasons.


3. Aluminum Sulfate

Aluminum Sulfate

A skimmer will not pick up any pollen that is too small for your pool. It may pass through the filter as if it was never there.

Aluminum sulfate can be added to water to get rid of the tiny pollen. The aluminum sulfate will bond with pollen, causing it to stick together and make it more difficult for the filter and skimmer to remove it.


4. Vacuum

Sometimes, skimming or filtering is not enough to remove all pollen from your pool. You may need to manually vacuum your pool if this is the case.

It is not a good idea. This will increase your water and electric bills. The vacuum will require more power to operate and the pool water will need to be replaced.


5. Cover

One of the best ways to reduce pollen in your pool is to install a Pool Cover. This will create a barrier between the water and the outside environment, preventing pollen from blowing into the pool.



You should be ready for the pollen season and take all necessary measures to get rid of it. While skimming and filtering can be sufficient, there are times when you will need to manually vacuum your pool. These five steps will ensure that your pool is pollen-free throughout the year.
