If you own a pool, you want to make sure you’re not inviting Algae to your pool party!

I know you’re disgusted by the thought of algae, but they can grow into any swimming pool. Luckily, there are ways you can get rid of it easily. In this article, I’ll cover all the ways you can get algae out of your pool, without using a vacuum. So, sit tight and read carefully.

Are you ready? Then let’s dive in.

What Exactly is Algae?

Algae are one of those unwanted guests that you wouldn’t want near your house, let alone in your pool. They can grow easily, which makes them a little hard to keep away.

Algae are a type of living creature that grows in water bodies. It starts with spores and starts to replicate itself if exposed to sunlight.

Since it has chlorophyll, it also undergoes the photosynthesis process. This takes place when it gets direct sunlight.

How Does Algae Form in a Pool?

The main cause of algae growth is through algae spores. These are usually blown in with the wind. They can also travel through swimsuits or swimming gear.

Maybe you wore your swimsuit and swam inside another pool recently. Your clothing might catch on these algae spores.

Algae can be transferred though swimsuits and pool cleaning equipment

If you didn’t wash your swimsuit after returning from another pool, then the spores can very easily travel to your pool once you take a dip in it.

Other than this, pool cleaning equipment can also cause the transfer of these algae spores.

Algae need a certain environment to grow rapidly, and this includes:

  • pH-unbalanced water
  • Warm temperatures
  • Excessive sunlight
  • Presence of certain compounds inside the water

Apart from these, lack of filtration and sanitation in your pool can also make it a breeding ground for algae.

If your pool is used by numerous people, then the algae has a higher chance of growth. It feeds off the bacteria and contaminants that travel with the people’s bodies.

What’s worse is that algae are present at nearly every swimming pool. Since they’re really small at the beginning, this makes them hard to detect.

All algae needs are the right conditions to grow.

What Problems are Caused by Algae in a Pool?

Due to the algae growth in your pool, no one will want to swim in it anymore. If not treated, the growth can increase rapidly and spread all around the pool.

Once the algae spreads, it can be nearly impossible for you to remove all of it. Moreover, it’ll cost you a lot of money.

Even if you get rid of the algae, you’ll have to keep up with the treatment to ensure that its growth doesn’t happen again.

Although algae aren’t directly harmful for people swimming in the pool, they can cause the water’s appearance to become cloudy.

So, you won’t be able to see from a distance if someone is about to drown. Plus, algae-infested pools can also lead to the growth of pathogens or illness-causing bacteria.

Algae also expels carbon dioxide when it’s undergoing photosynthesis. This leads to a shortage of chlorine in the water, causing the pH to become unbalanced. This makes it unsafe to swim, especially for children.

Therefore, it’s important to get rid of the algae inside your pool.

How to Get Algae Out of your Pool without a Vacuum?

Once the algae starts to grow, you need to nip it in the bud and keep it from spreading.

Typically, there are three types of algae that you’d find in your pool: green algae, black algae, and yellow algae.

Let’s discuss how you can remove each type of algae if you don’t own a vacuum.

Make sure not to drain out your pool, because it can cause the algae to get stuck in your pool’s filtration system.

Green Algae

This is the most common type of algae. They can either be green or blue in color, depending on how long they’ve been growing. They stick to the walls and crawl their way throughout the surface. They can also dislodge themselves from the wall and float on the surface of the water.

To remove green algae, all you need is a scrubbing brush and some household borax solution.

You have to apply borax to the algae-infested surfaces and scrub them really hard with the brush. This will cause the algae to come loose, and you can collect it with a net or scoop it up.

The borax will kill the algae and prevent them from growing. This makes it easier to remove the algae completely from your pool.

Black Algae

Black algae are one of the most stubborn and tough types of algae that you’ll find. This makes it all the more difficult to clean up.

If you notice black spots on the walls of your pool, it’s a sign that black algae have found their way to your pool.

Thankfully, all you need is a stiff brush and some baking soda. It has an active ingredient called bicarbonate, which stops the growth of algae and causes them to break away. Simply sprinkle baking soda on the pool walls and scrub them really well. Make sure to get every last spot of the walls, otherwise the algae may regrow in some time.

Once you’re certain that you’ve gotten the entire algae dislodged, you can collect them with a net.

Yellow Algae

Last but not least are the yellow or mustard algae. They can grow really deep. However, they’re less stubborn or tough than the other two forms of algae.

You’ll need the same stiff brush for the cleaning. You can also use baking soda to remove the algae effectively. Repeat the same steps that you did to remove black algae, and you’re good to go!

How to Prevent Algae Growth in Your Pool?

How do you prevent algae from coming back?

There are numerous methods you should implement regularly to keep algae away from your pool. One of them is to test your water regularly.

If it has a higher or lower pH level, then you need to change it immediately.

Also keep an eye on your filter. Make sure that it’s cleaned periodically. If you don’t clean it, algae spores can make their way to your pool. They’ll start collecting underneath the filter and spread rapidly.

Use multipurpose pool cleaning solutions. They are also repurposed to prevent the growth of algae. By following these steps, you’ll be able to keep algae away from your pool for a long time.


Although algae isn’t deadly or harmful, their presence can be quite unnerving. Plus, they can cause health-related issues. So it’s better to follow the aforementioned methods to get rid of them.

I hope this article helps you understand how you can get rid of algae from your pool, and also prevent them from making a comeback.
