How It Works

When pH in spa water drops below the ideal range, the water moves out of balance and becomes less suitable for comfortable, efficient day-to-day spa care.

SpaCare pH Up adds sodium carbonate to the water to raise pH back toward the ideal range of 7.2 to 7.6, without increasing alkalinity. This allows pH to be corrected more directly while maintaining overall water balance.

How to Use

• Test the pH of the spa or hot tub water.
• Determine the amount required based on your spa volume and current pH reading.
• Pre-dissolve the required amount in a clean plastic container of clean warm water.
• Stir well until the product is fully dissolved.
• Carefully add the solution to the spa or hot tub with the pump turned on, preferably near the water inlets.
• After a minimum of 6 hours, recheck the pH level.
• Repeat the treatment if necessary until the desired pH is obtained.
