Pool water treatment methods

For almost 60 years BAYROL have been experts in the field of pool water treatment. Based on this experience, BAYROL has brought three different reliable treatment methods to perfection. They guarantee clean and hygienic water quality, and are simple to apply at the same time.

In this section you will find:

1. Pool water treatment with chlorine
2. Pool water treatment with bromine
3. Pool water treatment chlorine free based on active oxygen
4. Chlorine stabiliser - with or without?
5. Copper sulfate in the pool water

Pool water treatment with chlorine

Chlorine is the most commonly used method for pool water disinfection. It is excellent for the oxidation of organic contaminants and destroys bacteria with the highest efficacy. Chlorine can be used for a continuous disinfection as well as for a shock treatment.

Who should choose chlorine?
Pool owners who want a safe and reliable disinfection method that guarantees hygienic water, and offers a good price-performance ratio.

Pool water treatment with bromine

Bromine has similar properties to chlorine in terms of reliable water disinfection. In comparison with chlorine, however, bromine is more effective at higher pH and temperature levels.

Who should choose bromine?
Pool owners who want reliable and continous disinfection without the chlorine odour. Ideal for disinfecting indoor pools and spas. Especially suitable for pools in hard water areas.

Pool water treatment chlorine free based on active oxygen

Chlorine free water disinfection based on active oxygen is the gentle alternative to chlorine. Water treated with active oxygen is soft to the eyes, skin and hair.

Who should choose active oxygen?
Pool owners who want crystal clear and pleasant pool water without the chlorine odour. Especially suitable for bathers with skin allergies.

Chlorine stabiliser - with or without?

Approximately 80% of all domestic pools worldwide are maintained with chlorine tablets made from trichloro-isocyanuric acid. The cyanuric acid (also known as stabiliser) reduces the natural decomposition of chlorine caused by heat and UV rays. It prevents that chlorine is consumed too quickly, and in consequence an insufficient quantity of disinfectant is present in the pool water.

To avoid too much stabiliser in the pool water, you should carryout a filter back wash at least once a week. The backwash should last between 3 - 5 minutes, and will replace approximately 3% of the pool water with fresh water.

If you want to avoid possible issues related with the over stabilisation of your pool water, simply use products without a stabiliser, e.g. Soft & Easy or  Softswim® based on active oxygen, Aquabrome® bromine tablets, Chloryte® calcium hypochlorite granules, or Chloriliquide liquid chlorine.

Copper sulfate in the pool water

Multifunctional tablets from certain manufacturers contain copper sulfate for the destruction of algaes. However, very few pool owners know about the negative impacts the use of copper based products in their pool could have:

  • Copper is a heavy metal and therefore harmful to the health.
  • Brown or black spots may occur in liner pools, which are difficult to remove.
  • Both plastic and metal parts of the pool pipe work system may be attacked (filter, pump, pipes).
  • Bathers with blond hair may suffer from green hair.
  • Bathing suits may become discoloured.
  • Pool water containing copper sulfate is considered harmful to the environment and should be disposed of through a sewage treatment plant. Under no circumstances should the water be drained directly into the ground!

For these reasons BAYROL products do not contain copper sulfate. All BAYROL products are free of any heavy metals.

Our recommendation: Take care and reconsider when buying multifunctional products containing copper sulfate!

Use biocides safely. Always read the label and product information before use.
