Is the pH value in your pool too low? Then use the BSI liquid pH Up to increase the pH of your pool water.
For example, if metal swimming pool parts oxidize and rust, this can result in brown spots. This means that the acidity is too low and that you should therefore use this pH Up. To be on the safe side, it is best to use the BSI Test Strips or Test Kit. It is important that you keep your pool's pH level between 7 and 7.6. Too high or too low acidity can cause irritation to the eyes and skin.
TIP!: Tap water can have a pH that is too high, rain and well water often has a pH that is too low. Keep this in mind when you top up your pool water so that you keep an eye on your pH value.
The BSI pH Up increases the pH value in your pool or spa:
