Our swimming pool cleaning tablets are carefully formulated with sodium dodecylbenzene sulfonate and disodium EDTA. Designed specifically to provide a constant chlorine dose, making the swimming pool water safer and cleaner. The usage method is extremely convenient: 1. Take an appropriate amount of this product, dissolve it in an appropriate amount of water, and stir evenly. 2. Add the dissolved solution evenly to the swimming pool at a ratio of 2 grams per cubic meter of water. 3. It is recommended to operate when the swimming pool is not in use. After adding the agent, wait for 60 to 90 minutes to allow it to dissolve completely and be distributed. And it can also reduce the amount of algaecides and flocculants used.
