pH Plus Granules – 5Kg

Used for increasing swimming and spa pool water pH levels when they drop to below 7.2.

It is imperative to check and correct pH levels regularly in order for the pool water to stay balanced and allow the chlorine to function efficiently.

Ideal pH levels are between 7.2 – 7.6 to promote:

  • Bather comfort
  • Optimal chemical efficiency
  • Protection of pool and spa equipment

All chlorine based sanitisers become less effective at killing bacteria and viruses as the pH decreases (becomes more acidic). 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). If spa water becomes less alkaline (above 7.6) it also gets more corrosive and less comfortable to swim in.

pH Plus Granules are also known as Sodium Bicarbonate
