Whenalgae appear in your pool, the first question that comes to mind is: how to get rid of them? And for good reason, whether it'sgreen algaeorblack algae, this phenomenon is a common problem in swimming pools.

To answer this question, it is important first to fully understand the underlying causes.An unbalanced pH, inadequate water circulation, or weather conditions favoring thealgae growthare generally responsible.

In the following lines, we will explain the reasons foralgae formationand guide you through the steps toclean your pooland prevent their return.

Why do I have algae in my pool?

The presence of algae in a swimming pool is a common concern, especially green algae, which are the most widespread. Their proliferation generally results from several factors, both environmental and technical. For example, after a period of rain, the imbalance of the water, particularly in terms of pH, can promote the appearance of algae.

The water temperature of the poolis also a determining factor. During hot periods, warm water and direct sun exposure provide ideal conditions for therapid multiplication of algae. Furthermore, insufficient water circulation, due to inadequate filtration or a lack of maintenance of the bottom and walls, facilitates the establishment of algae on the pool walls. If your water is subjected to these factors, it is likely that algae will develop.

Toeliminate algaeand get rid of it, it is essential to correctly identify the cause(s) of their appearance, in order to apply the appropriate treatments during the maintenance of your swimming pool.

Steps to Remove Algae from Your Pool

To eradicatealgae from your pool, you will need to perform a thorough cleaning and rigorous disinfection of the basin. Here are the steps to follow toeliminate algaeand prevent their return:

 

  • Brush and clean the pool: Start by thoroughly scrubbing thewalls, the bottom of the pool, the waterlineand the corners. Focus on areas where algae have accumulated. Use appropriate brushes to reach hard-to-access areas. Also remember to empty andclean the skimmer basket, where debris can accumulate.
  • Clean and disinfect the filter: The filter is essential for maintaining water quality. Clean it thoroughly with a disinfectant toeliminate algaeand other impurities. Then, let the filtration run continuously until the water becomes clear again.
  • Adjust the water pH: Anunbalanced pHpromotesalgae growth. Monitor your water's pH and adjust it between 7.0 and 7.4 for chlorine treatment, or between 7.4 and 7.6 for bromine treatment. Balanced pH will make your treatments more effective.
  • Perform a shock treatment: Ashock treatmentis essential to destroy impurities and microorganisms present in the water. Choose a product compatible with your treatment method (chlorine, bromine, active oxygen). Be careful not to use the pool if thechlorine levels are too high, and rebalance them if necessary.
  • Add an algaecide: To prevent algae from reappearing, use an algaecide product. These products are used to prevent algae growth.
  • Use a flocculant: To improve water clarity, place aflocculant cartridgein the skimmer basket every 7 to 15 days. The flocculant helps to clump together fine particles, making them easier for the filter to remove.
  • Filter continuously: After treatment, let the filtration run 24 hours a day until the water is crystal clear again. Once the water is purified, resume your usual treatment and filtration program. If necessary, replace the filter material to ensure optimal efficiency.

How to prevent the appearance of algae?

Have you managed to remove the algae from your pool? To prevent them from returning and thus, extend the lifespan of a polyester shell pool, a few simple but effective practices should be adopted throughout the year.

  • Maintain goodchemical balance: The chemical balance of water is the first line of defense against algae. Regularly use test strips or a test kit to monitor water pH, alkalinity, and hardness levels.
  • Monitor and adjust chlorine levels: Chlorine is a key element in disinfecting pool water and algae. A Chlorine Level residual between 1 and 3 ppm (parts per million) is ideal for preventing algae growth. Remember to test the water regularly, at least once a week, to ensure that chlorine levels remain within this range. If levels are too low, add stabilized chlorine to restore the proper concentration. During periods of high heat or heavy pool use, more frequent adjustments may be necessary to prevent algae from growing.
  • Ensuredaily filtration: Well-filtered water limits the accumulation of organic debris and particles, which reduces the nutrients algae need to grow. Remember to clean andmaintain the filtration systemregularly, by removing dirt and checking that it is functioning optimally, in order to guarantee efficient circulation
  • Use a preventative algaecide : In addition to chlorine, a preventative algaecide is an additional measure to prevent algae from settling. Weekly application of this specific treatment is particularly recommended during periods of high heat or rain, when algae are more likely to proliferate. There are different types of algaecides suitable for each treatment method (chlorine, bromine, active oxygen), and it is important to choose a product that is compatible with your disinfection system. Active oxygen can also be effective in combating and preventing the appearance of algae.

By combining these preventive measures, you can not only prevent the appearance of algae, but also ensure healthy and pleasant water for swimming throughout the season. Regular maintenance will allow you to fully enjoy your shell pool without the hassle of algae!
