How to clear a green pool in 3 days? Quick tips

Many pool owners find having a green pool to be both unattractive and unpleasant. It is brought on by a chemical imbalance and can cause your pool to abruptly change colour from sparkling blue to muddy green. A green pool can be cleared in just five days, so don't panic. One typical cause of green pool water is the presence of algae in your pool. Algae blooms may form if the free chlorine level in swimming pool is too low. You have a higher risk of developing pool algae if you are exposed to extreme heat, heavy rain, or poor circulation without using a prophylactic algaecide. Stubborn pool algae can be challenging to manage if the right procedures aren't taken to effectively treat and avoid the problem.   

Determine the colour:   

Teal green, Green, Dark green (black). Most pools are affected with the green pool, which is easier to clear, when the pool is found in black or dark green colour, it is generally difficult and requires more time, chemicals and process to clear them. Using pool shock with active component such as calcium hypochlorite shock does the job, it is best to have <60% to treat, water clarifier (will turn from green to grey after calcium treatment), so clarifier clarifies the grey.   

Note: Flocculant is not advised because it does not utilise the filtration system and simply pushes all the dirt to the bottom, necessitating vacuuming.   

Shock treatment at each stage:  

  1. Double shock if Teal Green 
  2. Triple shock if dark green 
  3. Quadruple shock if black/dark green.

NOTE: algaecide does not eradicate algae, but prevents them from occurring  

It takes persistence and careful upkeep to clear a green pool in just five days. In order to maintain the pool's health at its highest level, don't forget to test the water, shock the pool, brush and hoover it, correct the pH and alkalinity, add algaecide, monitor and regulate it. You can spend the entire summer in a spotlessly clean pool by following these instructions.    

Day 1: Test the Water and Shock the Pool, Adjust the pH and 

Your swimming pools pH and alkalinity levels are crucial in limiting the growth of algae. Algal growth may be encouraged by an environment where the pH and alkalinity levels are either too low or too high. The optimal alkalinity for pool water is between 80 and 120 parts per million, and the pH level is between 7.2 and 7.8. (ppm). To determine the concentrations in your pool, use a pH and alkalinity tester. Chemicals must be used to balance the levels if they are out of balance.  

Using a pH regulator will help balance the pH in the water to its optimal level. As an alternate adding baking soda or soda ash, you can increase the pH of your pool. Use sodium bisulphate or muriatic acid to reduce the pH level. Muriatic acid can be used to lower alkalinity levels while baking soda can be used to boost them

Water testing is the first step in cleaning a green pool. To assess the pH, alkalinity, calcium hardness, and chlorine levels of the water, you will need a test kit. You can begin treating the pool as soon as you obtain the results.   

For shock treatment, it is recommended to have pH lower than 7.0 and is great if it is between 6.7-6.8. You must shock the pool with chlorine to begin the therapy. To kill bacteria and algae, shock your pool by adding high concentrated chlorine to the water. The size of your pool and the level of green algae impact on how much shock is required.   

It is advised to employ a fast-dissolving, granular chlorine shock with at least 65% readily accessible chlorine. It is also best to follow the instruction given on the container. You'll save time and help avoid calculating errors by doing this.    

  • In a five-gallon bucket, pre-mix the pool shock.  
  • Verify that the pool pump is operating. 
  • The mixture should be poured into the water at the pool's margins. 
  • Allow the pump to operate for at least six hours. 
  • Make sure the water is properly chlorinated by testing it. 
  • Use the pool only when ready. Wait until the free chlorine concentrations reach 1 to 3 ppm. 
  • Work with pool chemicals while wearing gloves and safety eyewear.  

Day 2: Brush and Vacuum the Pool  

The second day, the change will be much noticeable as the water will be much clearer. To increase the efficiency of the shock treatment, vacuum the pool.   

Use the handle, unique hoover brush and vacuum inlet or skimmer adaptor.  Set the multiport valve to "circulation mode" and begin cleaning the pool's surfaces. It is crucial to backwash the filtration media after cleaning process, because all dirt remains in the filter unless it is back washed. Water loss is normal and expected. 

Dead algae will be floating on the water's surface after the pool has been shocked. To get rid of any last-minute algae, scrub the pool's walls and floor using a pool brush. This aids in limiting the growth of algae in the future. After brushing the pool, hoover up the dead algae on the bottom of the pool. Pool vacuums come in a variety of styles, including automated and manual vacuums.  

It is strongly advised not to use an automatic cleaner when it comes to warding off algae, since it will damage the robotic cleaner. Vacuuming through a filter system is much more effective in such circumstances. Make sure to hoover the entire pool, paying special attention to the steps and corners, where algae tend to form.    

Day 3: Repeat Day #1 Routine - Shock treatment and Algaecide   

The owner might in some circumstances require further shock chlorination. He should therefore carry out step Day #1 routine, which entails shock and pH level.  

The objective of shocking a pool is to increase the amount of free chlorine in the water to approximately ten times the amount of mixed chlorine. Chlorination breaks down once it reaches this threshold. It is best to shock a pool around dusk. Restabilized chlorine will be destroyed by the sun. Making sure the chemicals are working properly at night by shocking your pool (It's best to avoid, because it can damage the pool lining). 

Granular pool shock can be added directly to your pool; however, the majority of kinds require mixing with water before usage. If required, combine the granular pool shock and water ahead of time.   

For effective results, kindly follow the shock treatment steps provided in Day#1.  

It's possible that there are still some algae spores in the water even after you've shocked the pool and removed the dead algae. By eliminating any spores still present, adding algaecide helps to stop future algal development. Algaecide comes in the form of liquid, which comes in varieties of ingredients that contain copper and others that do not, which can be chosen based on the pool.  Make sure to thoroughly read the directions before adding any algaecide because different varieties of algaecide call for varying dosages depending on the size of the pool. It's also vital to remember that a pool may foam if an algaecide is added in excess.    

Swimming pool maintenance: Monitor the Pool and Adjust as Needed  

Your swimming pool should begin to appear cleaner and clearer after four days of treatment. To maintain a balanced pool, it is crucial to keep an eye on the water chemistry and make the required adjustments.  

Every day, check the levels of pH, alkalinity, and chlorine, and add the appropriate chemicals to keep them within the recommended range. To get rid of any last-minute particles, keep brushing and vacuuming the pool as needed.   

Quick recommendations to clear green water in three days

Day 1: ph, shock chlorine.

Day 2: Vacuum

Day 3: Repeat the day #1 if needed.
