HTH pH Plus Powder 5kg is used for raising the pH levels in your swimming pool or hot tub spa. Maintaining the correct pH levels in the water is important as low pH levels can cause eye and skin irritation and cause corrosion and damage pumps, heaters and even the pool finish.

pH levels show whether the water is Acidic or Alkali. Low is Acidic and High is Alkali
