Customer Questions
- Test the PH of your pool or hot tub regularly (depends on usage but at least once a week). The PH should always been maintained at between 7.2 and 7.6.
- If your test kit reading indicates that the PH of your water is lower than 7.2, add PH Plus at a rate of 10gm per 1000 litres of pool and hot tub water (e.g. if your pool or hot tub contains 7,000 litres then add 70g of PH Plus). One heaped teaspoon holds approximately 9gm of PH Plus.
- Pre-dissolve in a clean bucket. Add directly to the water for hot tubs.
- Ensure the circulation pump or system is running when adding PH Plus.
- Slowly pour into water immediately above the pool return inlet or hot tub skimmer.
- Test PH regularly and repeat dosing until your PH reaches 7.4.
- Never add product when pool or spa is being used; do not allow pool to be used for 15 minutes after adding PH Plus.
