AquaSPArkle Spa pH Plus contains: Sodium Carbonate.


All chlorine-based sanitisers become less effective at killing bacteria and viruses as the pH rises (becomes more alkaline). Acid/Alkaline conditions are measured on the pH scale which ranges from 0 - 14. Ideal bathing conditions exist at a slightly alkaline level of 7.2 to 7.6 with Total Alkalinity of 80/140 mg/l (ppm).


Ideal pH Range: 7.2 – 7.6


Test the pH of your spa water and if it is below 7.2, use AquaSPArkle pH Plus to raise it.
