Checklist For Chlorine Tablets For The Pool

Continuous or Shock Chlorination?
  • Shock or surge chlorination is a short burst of chlorine: when refilling, after a party, in case of infestation by mosquito larvae or other acute loads. Continuous chlorination helps with constant high loads. Here you chlorinate permanently.
  • Accordingly, you need slow or fast dissolving tablets. Granules are also suitable for shock chlorination.
  • Do you want both? There are mixed tablets: One half dissolves immediately, the other only slowly.
What is your purpose?
  • Do you only want to disinfect? Or additionally an algae killer, pH stabilizer or flocculation: Here multifunctional tablets with appropriate additives are suitable.
Inside or Outside?
  • You need a different type of chlorine for indoors than for outdoors. Will the chlorine be exposed to the sun? Then use stabilized chlorine!
  • Non-stabilized chlorine should only be used at night or indoors. It decomposes quickly and is good for shock chlorination.
What is active chlorine?
  • Active chlorine is in contrast to combined chlorine: if it binds to dirt or bacteria, it is no longer effective. Active chlorine is also called free chlorine. It can be up to 90 percent of the tablets. However, certain additives can reduce its effectiveness.
  • Nevertheless, additives are useful.
  • Algaecide, for example. Or cyanuric acid: it stabilizes chlorine for permanent use.
How many tablets do you need?
  • The size of the tablets should fit the pool. The manufacturer’s specifications provide orientation: A slowly dissolving tablet of 200 g should be sufficient for 30 m³ for an average of one week. Round up, if you need more: About 80 m³ to 90, makes 3 tablets.
  • Small tablets of 20 g or large tablets of 200 gare common. Ideally, they should be individually wrapped so that they can be stored for longer.
Safety
  • It is better to buy products from the EU! Asian tablets are cheaper, but sometimes have defects due to differentiated standardization.
  • Not all tablets belong in the skimmer. Certain ingredients could damage the system! Information about this can be found in the product description. Then use accessories, such as a floating dosing unit.
