Practical 20 g Chemochlor T tablets are used mainly to maintain the desired chlorine level over the long term during the swimming season. The tablets are usually dosed into a skimmer or a floating dispenser, where they dissolve slowly and provide a continuous disinfecting effect.
Recommended use may vary depending on pool volume, water temperature, bather load, and target values (especially pH and free chlorine). For best results, follow the instructions on the label of the specific product batch.
