HTH pH Plus Powder will quickly raise the pH levels in your swimming pool or hot tub spa. Having the correct pH levels in your pool and spa 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 pool or spa water is Acidic or Alkali. Low is Acidic and High is Alkali

How To Increase pH Levels in Swimming Pools using HTH pH Plus Powder
To increase pH in pool water by 0.2 Add 300g per 20,000 litres (20m3) 

With the pumps running sprinkle HTH pH Plus Powder evenly around the pool, but not into the skimmers.

Leave the filtration running and re-check the pH levels after 24 hours. If required re-dose with HTH pH Plus Powder using the same process.
