The correct pH value is a basic requirement for clean jacuzzi water. When the pH value is correctly adjusted, the cleaning chemicals work effectively and the water stays clear for a long time. Start by testing the pH of your water using test strips to find out if the pH is too high or too low. The target value is 6.8-7.6. If testing shows a pH greater than 7.6, add pH minus gravel to the pool water to lower the pH to an appropriate level.
Note! Leave the lid open for at least 15 minutes after adding the product.
