Spa Pure pH Down
pH is a measure of the acidity of the water. pH should be maintained at 7.4 to 7.6 for optimal sanitizer effectiveness, protection of hot tub parts and equipment, and user comfort.
If the pH drops below 7.4 the water is too acidic. This can corrode the spas parts and equipment and cause eye and skin irritation.
If the pH is above 7.6 the water is too base or alkaline. The sanitizer will lose some effectiveness, and minerals can fall out of solution which can cause cloudy water, scale build up (the feeling of sand paper on the spa shell) and equipment damage.
- Spa Pure pH Down is used to lower the pH in hot tub water
- Helps to reduce corrosion of metal parts and damage to pump motors and heaters due to low pH
- Fast dissolving
- 1-1/2 Pounds
- If a test kit ready indicates that the pH is greater than 7.6, sprinkle one tablespoon of pH Down per 500 gallons of spa water. Wait two hours and test again.
