How to Remove Algae From Your Pool Without a Vacuum Quickly

As a pool owner, you are in the eternal fight against algae in the pool. Usually, a pool vacuum is used for this, but how can you remove the algae without a pool vacuum?

The best way to remove algae in the pool is to use a pool brush and keep the filter run times above 6h/day. A pool shock, some algaecide, and the use of flocculants make cleaning easier without a pool vacuum.

This article is about removing algae in the pool and keeping them from reoccurring in large quantities.

Why does your pool get algae?

There are several reasons why your pool may get an algae bloom.

Mostly that’s because of how much sunlight is getting into the pool and how much phosphate is in the water.

If you protect your pool from direct sunlight, it helps trigger algae growth. So if you reduce the sunlight as much as possible, it can help limit how often you have to remove algae from your pool.

Phosphate is one of the most common reasons you have algae bloom in your swimming pool.

This is something you can prevent very easily by not using phosphate-heavy cleaning products in your pool.

But too much sunlight and phosphate in the pool water are not the only reasons why you have algae in your pool.

In most cases, a short pool pump running time is the main cause because the water has to be circulated daily – I explain in my other post how long should your pool pump run.

Just remember: Moving water is living water!

A too high or too low pH level is also a reason for algae in your swimming pool. If the pH is below 7.0 or above 7.6, you have to expect algae.

If your local water company adds more phosphate to the water, then there’s not that much you can do about that. If that’s the case, your water treatment has to be taken to the next level.

So take care of your water balance in your pool. In my blog, I describe what pool chemicals you need for this. Use the search function to find my complete guide.

Do you have to vacuum algae out of a pool?

Usually, the algae are loosened from the floor with a pool brush and later removed with a pool vacuum.

I have to mention: A vacuum is not the only solution to get rid of the algae in your pool. You have to keep an eye on the water balance and probably shock your pool to kill the algae.

But, to answer your question.

No, You don’t have to vacuum algae out of your pool. With a proper sand filter and the right chemicals like a flocculant, you will get rid of the algae in your pool.

This only becomes difficult when the algae are firmly attached to the floor and walls.

In this case, a pool vacuum is very effective for removing algae, but how can you remove the algae without a pool vacuum?

It’s not that easy to remove the algae without any tool.

Even if you use an algaecide in your pool, it will take some time before all of the algae is gone.

How about installing a robot pool cleaner to avoid this mess and frustration?

Robot pool cleaners are the best way to remove algae from your pool. Some of them can even suck up small rocks or pebbles, so there’s no need to pick them manually. Additionally, some robot pool cleaners have different kinds of filters, which may remove more particles than a manual vacuum.

Maybe a pool robot is too expensive for you. In this case, you will find further instructions on how to remove algae in your pool without a pool vacuum.

How to remove algae from the pool without a vacuum

  2. Use a chlorine shock or bleach to shock your pool.
  3. Let the filter run while you shock your pool.
  4. Scrub the entire pool to loosen the algae.
  5. Use an algaecide to inhibit the growth of algae.
  6. The pool filter must run for 24 to 36 hours.
  7. When the time is up, check to see that all the algae have been removed from the pool.
  8. Have all the algae been removed? If not, repeat all steps.

That’s it!

You have successfully removed the algae in your pool without a pool vacuum.

Removing dead algae from pool bottom without a vacuum cleaner

My instructions to remove the algae from your pool are helpful, but maybe some dead algae are left behind in your pool.

You still don’t have a pool vacuum and want to know how to remove dead algae from the pool bottom without a vacuum cleaner?

  1. Brush the pool surface with a pool brush.
  2. Add some flocculant to your pool to bind the dead algae.
  3. Let the filter run for 24 hours to remove dead algae from the pool bottom.
  4. If you want, you can add another chlorine shock or algaecide in your pool, but I think you don’t have to.

All of this is easier with a good robot pool cleaner.

How to remove algae from a kiddie pool

Removing algae in a paddling pool is easier than in a large swimming pool.

  1. First, drain the kiddie pool and remove all of the contents.
  2. Use a brush to scrub the entire surface.
  3. Clean it with a garden hose to ensure your paddling pool is clean.
  4. Then fill the paddling pool with water again.
  5. Make sure the pH level in your kiddie pool is between 7.2 and 7.4 so that the children’s eyes do not sting.

Don’t use a pool shock in a kiddie pool because large amounts of chlorine are dangerous for your kids!

Small paddling pools can simply be emptied and refilled every 2 to 4 days. This is still justified even with the smallest Intex pool.

If you want to learn more about how to clean a small above-ground Intex pool, read my full guide under the link.

Will vinegar kill Algae in your pool?

You may have noticed that some home remedies can be used for water maintenance.

I am often asked whether vinegar can kill algae.

No, vinegar is not effective against algae.

Still, some people think you can remove the algae by adding some vinegar to your pool. But that is not true!

Stick with the proven method to kill the algae in a pool, and everything will be fine.

But, it doesn’t matter how you do it. If you fail to maintain the right pH level in your pool, it will be green again.

How to keep algae out of the pool?

The best remedy against algae is not to let it develop in your pool.

Do you agree?

Then follow the instructions below to keep algae from growing in your pool.

  1. Test the pool water (especially the pH level, alkalinity, and calcium hardness).
  2. First, you have to balance the alkalinity to 80 – 120 ppm.
  3. Then, balance the pH level to 7.2 – 7.6. The best way to balance the pH is by using a pool tester, which you can purchase in any sports shop for less than $20.00.
  4. After that, you have to balance the calcium hardness to 200 – 400 ppm.
  5. Add some chlorine or another pool chemical to disinfect the water.
  6. Use some algaecide to inhibit algae growth.
  7. Apply a flocculant into the pool water to improve the water filtration.
  8. Scrub your pool daily and let the filter run every day for 6 to 8 hours.

You have to test your pool’s water every day during swimming season, especially after heavy rain or adding chemicals. To keep it simple, just stick with the method above.
