HTH SPA pH Plus Powder pH Increaser  uses soda carbonate to balance the pH level in your hot tub spa, so that the chlorine is sanitising efficiently and that the water is comfortable for bathers to use.

Using HTH SPA pH Plus Powder to increase the pH in your hot tub spa is an essential part of your maintenance that will help balance the pH in the water.

HTH SPA pH Plus Powder pH Increaser should be used to correct the pH in spa water when it falls below 7.2.

Acidic spa water is uncomfortable to bathe in, as it may cause sore eyes and breathing issues, and if left unchanged, can cause corrosion of metal parts and fittings. pH Increaser (pH plus) works to increase your spa water pH balance using soda ash.

Take a pH reading using test strips or test tablets. Increase the pH if the reading is below 7.2.

How to increase pH in spa water with HTH SPA pH Plus Powder:
Dose rate is 15g HTH Spa pH Increaser per 1,000 litres (220 galls) of spa water. Each dose increases the pH by approximately 0.2.

With the pumps and jets running, dose directly over the surface of the spa water, avoiding the skimmer. Dose only when bathing has ceased. Continue filtration & re-test after 15 minutes. Repeat treatment until the pH falls within the range 7.2-7.6.

Contains Sodium Carbonate.
