Happy Hot Tubs PH Minus –

Use this high quality PH Minus to decrease the PH value of the water in your spa (7.2 to 7.6 is the optimum for spas). PH Minus is also used to decrease the total alkalinity of your spa, hot tub or pool water. Simply test your hot tub or swimming pool water and follow the instructions to decrease your PH correctly.

1. 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.
2. If your test kit reading indicates that the PH of your water is higher than 7.6, add PH Minus at a rate of 10gm per 1000 litres of pool and hot tub water (e.g. if your pool or hot tub containns 7,000 litres then add 70g of PH Minus). One heaped teaspoon holds approximately 9gm of PH Minus.
3. Pre-dissolve in a clean bucket. Add directly to the water for hot tubs.
4. Ensure the circulation pump or system is running when adding PH Minus.
5. Slowly pour into water immediately above the pool return inlet or hot tub skimmer.
6. Test PH regularly and repeat dosing until your PH reaches 7.4.
7. Never add product when pool or spa is being used; do not allow pool to be used for 30 minutes after adding PH Minus.
