Pollen in Pool (Get Rid of Them in 3 Steps)

Pollen is an annual problem that every pool owner has to deal with.

But how does so much pollen end up in the pool, and how can you get rid of it quickly?

This article explains how you can quickly get rid of pollen in the pool.

Why is there pollen in your swimming pool?

It is a normal process as pollen floats around in the air and comes into contact with water.

In most cases, pollen ends up in your pool through rainwater, but it could also have been blown by the wind directly onto the surface of the water.

In addition to this, pollen can easily come off of leaves or other plants which fall into the pool during a storm.

So, if there are many trees and other plants near the pool, the pollen from them will be blown directly into your pool with the help of the wind.

The good news is that it’s nothing to be worried about, as pollen are just tiny parts of plants that are easily removed from your swimming pool by the filter system.

As long as there isn’t too much pollen, this cleaning process will happen quickly.

However, if you have a lot of pollen in your pool water, you should be concerned about two things.

  • Firstly, the pollen can trigger allergies if you or your family members are allergic to pollen.
  • Secondly, if too much pollen is in the water, this could clog up your filter system. This is why it’s important to try and remove as much of the pollen as possible before it reaches the filter system.

Is that pollen in your pool or algae?

Often beginners make the mistake of identifying pollen in the pool as algae.

In the worst case, too much algaecide is dumped into the water, and no effect is achieved. This is a waste of money and can cause the pool to foam.

However, it is easy to distinguish between them by following this guide.

Pool with algae:

  • The pool has a green or light blue color.
  • Algae feel slimy.
  • Dirt particles are clearly visible (even when water is crystal clear).
  • The pool water smells bad.

Pool with pollen:

  • The pool has a brown or yellow color.
  • Pollen feels slippery, but it is not slimy.
  • Soil particles are visible (when water is cloudy).
  • The pool water has no bad smell.

I often get a question: Does pollen sink to the bottom of the pool?

Some swear that it does, while others don’t think they’ve seen pollen at the bottom of their swimming pool.

Maybe it is just sand in your pool, and you do not see pollen at all?

You can easily test this by taking a pool brush and briefly scrubbing one spot. If heavy clouds form at the spot, then it is probably pollen.

You now know where the pollen comes from, and you can distinguish them from algae.

But how do you get the pollen out of the swimming pool?

How to remove pollen from your pool?

Is the entire water surface covered with a yellow layer of pollen? If yes, then take a fine landing net and first try to remove as much of the pollen as possible by hand.

This is important so that your filter system does not clog unnecessarily, and you must backwash your sand filter continuously.

After that, you can follow these instructions to get rid of the pollen quickly.

  1. Start your pool pump and let the skimmer do the work for you. After a short time, you will see that the water is slowly clearer. At this point, you should be very careful! If there is too much pollen in the water and it is sucked up the skimmer by the pool pump, it can cause problems for your equipment or even damage it. So make sure to stop your pump as soon as the water is clear.
  2. The skimmer basket can be emptied halfway with a plastic container, or you can filter it later through a fine net. But whatever you do: Don’t forget to stop the pump before removing the skimmer basket!
  3. If there was not too much pollen in your pool, this should have been enough, and you can return to normal pool care.
  4. If the pool is still slightly cloudy from the pollen after filtration, you should place a flocculant pad in the skimmer to improve filtration.
  5. Check if pollen has also accumulated on the bottom of the pool. You must remove them through the floor drain or use a pool vacuum in an above-ground pool.

After that, your pool should be clean again.

To be absolutely sure that your water does not turn green due to the excess of foreign matter, you can use a pool shock.

If you have removed the pollen in time and the filter system continues to run for 6 to 8 hours a day, a pool shock should be unnecessary in most cases.

What happens if the pollen stays in the pool too long?

The pollen is a foreign substance and disturbs the water balance in the swimming pool.

They provide a food base for bacteria (which consume large amounts of oxygen in the decomposition of pollen in the pool), algae, and fungi. The water balance can not handle this sudden pollen concentration, so it chokes the chlorine off in the pool.

This creates an imbalance in the chemical equilibrium in the water, leading to reduced transparency of the water.

As a result, a simple problem with pollen can quickly turn the entire pool into a green mess full of algae.

The result is that you have to spend significantly more time and chemicals cleaning such a dirty pool.

Therefore, you should quickly get the problem with pollen in the pool under control.

Pollen Season: How to prevent pollen in the pool?

We have successfully eliminated pollen in the pool, but pollen season is not over yet.

To prevent your pool from being covered with a yellow layer of pollen again, you should take the following steps to avoid the hassle of pollen in the pool.

  • Use a pool cover: The best way to prevent pollen in your pool is to use a pool cover. A solar pool cover will help to keep your pool warm while preventing the water from evaporating and keeping pollen out of the water. A solar blanket can also be used but should not be used when swimming because it makes moving in the pool hard.
  • Use a pool landing net: Use a fine mesh pool landing net to clear the water manually.
  • Add a pool clarifier: Add 1-2 quarts of Clarifier into your pool after each rain or power washing. A pool clarifier will help the filter system work more efficiently in removing pollen from the water. Clarifiers pick up small particles that can cause cloudy water, including pollen.
