Did You Know? Scale in hot tubs is created by the sodium bicarbonate dissolved in the spa water separating into sodium carbonate. Sodium carbonate has an affinity for calcium in the water. When sodium carbonate and calcium dissolved in the spa water join together, this particle size is large enough that it becomes visible (precipitation) and creates the result of scale. The good news is that this process can only happen at pH 8.3 or higher.
