Pool chemicals for clean, balanced water

The most common types of pool chemicals are:

  • Chlorine is the most common disinfectant for pools. It is effective against bacteria, algae and other microorganisms. Chlorine is available in various forms, including liquid chlorine, tablets and granules.
  • Bromine is another effective option for pools. It is similar to chlorine but is less irritating to skin and eyes. Bromine is available in liquid form.
  • Ozone is an effective disinfection method that produces no by-products. However, it is more expensive than chlorine and bromine.

In addition to disinfectants, other chemicals help keep pool water clean and fresh. These include:

  • Alkalinity regulators help keep the pool water's pH at the correct level. The pH should be between 7.2 and 7.8.
  • Flocculants help remove small particles from pool water.
  • Algaecides help prevent algae from growing in the pool.
  • Dyes can be used to give pool water a particular colour.

It is important to follow the chemical instructions carefully. This ensures the pool water is safe to swim in.

Here are some tips for using pool chemicals:

  • Read the chemical instructions carefully before use.
  • Use the correct amount of chemicals. Using too much can be harmful to people and the environment.
  • Test the water regularly. This helps ensure the pH and other chemical parameters are at the correct levels.
  • Follow a regular maintenance schedule. A consistent routine helps keep the pool water clean and fresh.

By following these tips, you can keep your pool ready for swimming.



Choose chemicals based on measured needs and the dosing system

Pool chemicals serve different purposes, such as pH adjustment and algae treatment. Base your choice on current water test results and the product label. A liquid product intended for an automatic dosing unit must match the unit's instructions and materials, not simply the container size.

The category includes liquid pH-minus in 20-litre containers and ALGICID. They serve different purposes and are not interchangeable. Check consumption, shelf life and suitable storage before choosing a pack size. Follow the dosage for the specific product; guidance for another concentration or pool volume can be misleading.

Check before changing the treatment

Note the pool volume, current treatment method and latest readings. If the automatic system gives unusual readings, check sensors and calibration according to its manual. For equipment, see automatic pool dosing, and for measuring and service parts, see pool dosing accessories. Always follow the product's use and storage instructions.
