Step by Step Process to Clean Pollen from Pool Water

Pollen settling on the surface of your pool water can make your pool look like something from a zombie apocalypse movie. Let’s take a look at what you can do to get rid of it.

The most important thing at this stage is to understand the following points. It is not very difficult to get rid of, as long as you work on it a little every day, during the periods when the pollen is abundant.

1. Operate your filtration

Most of the time, it is not necessary to run your filter 24 hours a day, 7 days a week. But when you have a pollen problem, the filtration system is your best defense in removing it from the surface of the water.

If necessary, put it on forced and continuous, the time to skim the surface. This may not be enough, but it is the first instinct to adopt.

As the pollen deposit is subjected to the sandstones of the wind, it may also be necessary to temporarily modify the direction of the water jet from the discharge nozzles. The idea here is to reach the dead zones of the basin to force the pollens to go towards the skimmers.

Do not forget to open the skimmer valves to 100% and the bottom drain to 50% if there are bottom deposits.

This will greatly reduce the amount of manual labor required to rid the pool of this pollen.

Of course, throughout this phase, check the state of the pressure of the filter (manometer) and the amount of waste in the baskets of the skimmers or the pump pre-filter. Clean them as soon as they are too dirty.

2. Skim the water regularly

Every morning (and maybe the afternoon too), take a very fine-meshed landing net and put it in the water to collect the pollen that has accumulated overnight.

Unfortunately, you will have to repeat this process more than once a day during periods of high pollen distribution.

Remember that an ordinary landing net is generally not as effective as its mesh/braiding is often too large to trap pollen.

At a minimum, you have to push as much pollen as possible into the water flow that goes from the delivery nozzles to the skimmers. Without forgetting to clean the water line if necessary.

3. Aluminum sulphate

Some pollens are simply too small to be captured by a dip net. They will even pass through the filtration system and return to the pool.

To get rid of this type of pollen, you can add aluminum sulfate to your water. It has the effect of clumping the pollens together to form a thicker substrate.

The filter and the landing net can thus capture them more easily. The landing net allowing them to be completely removed from the filtration circuit.

4. Shock the pool

When fighting pollen, it’s a good idea to shock the pool at night, before going to bed.

It will kill whatever has made your pool a good place to call home, because of the pollen floating around in the water.

With the filtration working continuously overnight (if you leave it running – recommended) or restarting it the next morning, you will be able to more easily remove whatever is left in the water.

5. Vacuum if necessary

Sometimes simple surface skimming and continuous filtration are not enough. If the pollen is particularly heavy in your area, you may need to vacuum the pool manually.

Do this as a last resort and only if necessary, so as not to consume water and electricity unnecessarily.
