How to Clean a Green Pool With Bleach Effectively in 4 Steps

It’s normal to be worried when your pool color turns green. You must investigate the underlying causes of the problem. It’s quite hectic to clean the pool when it’s covered with algae and turned green. The great news is, the solution is near you, it’s bleach!

How to clean a green pool with bleach?

Firstly, you have to find chemical equilibrium. Then clean the pool by adding a cyanuric acid concentration. Don’t forget to shock the pool afterward. Set up a timer and let the water run for a few minutes. Ensure that the bleach is evenly mixed with the water. Measure the tool for proper cleaning. 

For knowing more, I hope you’ll stick around!

The Factors Behind Your Pool Turned Into Green

The water in a swimming pool must be regularly maintained in order to be safe for swimmers.

Your pool water turned green because of algae, as you may have guessed.

It’s a symptom of a chemical imbalance. Algaes are killed by the bleach that you mix with the water. If the chemical level isn’t ideal, they will quickly infiltrate your pool.

There are some other reasons for your pool to turn green:

When The Pool Filtration System is Broken

When the water is not filtered thoroughly because of a damaged pool filtration system, it will become grosser and the chemicals will not be evenly distributed.

Forecast Conditions 

During humid weather, algae thrive and grow more quickly. The typical chlorine dosage may not be enough for cleaning. It happens when the algae growth is exceeded. 

Visible Wastage in The Pool

Visible waste can introduce algae to your pool’s water. Algae can grow on outside wastes that are in your pool. It’s important to remove these wastes so that you can control algae growth.

You need to fix it immediately because it’s dangerous for your health. Fortunately, as demonstrated in the guidance below on how to clean a green pool with bleach. You can do it on your own.

How to Use Bleach to Clean a Green Pool With Easy 5 Steps

Keeping a swimming pool clean, especially when it’s infested with green algae, is a time-consuming task. You can use household bleach.

Also, the pool maintenance cost is not expensive. In order to make things simpler for you, we’ve put together the following how-to.

Step 1: Find a Chemical Equilibrium.

Checking the pH and alkalinity levels, which are between 7.2 and 7.8 and 80-120 ppm. 

It’s essential that we know the additives have the ability to kill algae or other harmful microorganisms.

Any pH level above 7.8 diminishes its efficacy. Use a pool test kit to find out what these levels are.

Sodium bicarbonate should be added if the pH level is less than 7.2.

Dry acid, also known as muriatic acid can be used if the pH is above 7.8. If you want to know exactly how much of each chemical is in your product, this handy tool can tell you.

These are some suggested chemical test kits for your pool:

Product 1
Product 2

These products will help you to test the chemical balance of your pool.

Step 2: Time to get the pool cleaned up!

Use a pool cleaning brush to remove any algae from the pool’s walls, floor, liner, grout, and ladders before shocking the pool.  

The base of the pool needs to be cleaned as well to remove the buildup of sediment. 

These tasks are critical because they aid in the bleach’s ability to work.

Step 3: A Cyanuric Acid Concentration Test 

In order to generate a sparklingly clean pool, bleach requires cyanuric acid concentrations of 20 to 50 parts per million (ppm). 

All you have to do is get a toolkit and take measurements of cyanuric acid concentrations.

If it goes below the minimum, add a stabilizer. You should read and follow carefully the stabilizer product label instructions.

Step 4: Calculate the Pool’s Volume

This information is crucial in determining the portion of bleach needed. Check out how much bleach you need to get you started.

The next step is shocking the pool. In order to shock a pool, the free chlorine level must be increased from 1-3 ppm to 5-10 ppm. 

Use 30,000 gallons of water and 5 gallons of chlorine bleach to accomplish this.

Step 5: Use Shocking System

Bleach degrades in the sunlight, so shock your pool in between the afternoon or early evening. 

Get the water moving for about 4-5 hours to make sure that the bleach is properly dispersed. 

Then, walk around the pool and add the bleach. If you don’t remove the cloudy water from the pool within 24 hours, you’ll have a problem.

After approaching the above instructions, you should have no trouble cleaning your green pool. Using these simple guidelines, you can keep your pool sparkling clean. You can use the same method to clean your roof.


Question: Why is my pool green with high chlorine?

Answer: When the chlorine levels are imbalanced, which can make the metals in pool water oxidized, turning the water a different hue of green.

Question: Why did shock turn my pool green?

Answer: You see your pool turned green because of copper oxidation by shock chlorine. The best way to get rid of it is to raise the calcium hardness of the pool by adding calcium chloride to it.

Question: Can I use household bleach in my pool?

Answer: To sanitize a swimming pool, you can use any of these products: household bleach, Clorox, or liquid chlorine. All of them are chlorine. Household bleaches such as Clorox usually contain about 5-6% available chlorine, about half that of pool liquid chlorine. 


That’s all I have to say about how to clean a green pool with bleach. I hope you now understand the issue at hand.

Consult an expert if the problem persists despite your best efforts. Use the chemicals with precautions.

My best wishes for a quick resolution!
