Natural Chemistry Calcium Increaser | 1.83 lb Bottle | 14205NCM

Maintain the health and longevity of your spa or hot tub with Natural Chemistry Spa Calcium Hardness Increaser. This powerful formula is specially designed to raise calcium hardness levels, helping to prevent damage to spa surfaces, plumbing, and equipment caused by corrosive, low-calcium water.

When calcium hardness drops below the recommended range of 150–250 ppm, your spa water can become aggressive—leading to cloudiness, surface etching, and costly repairs. Natural Chemistry’s solution restores balance, protecting your system and ensuring a safe, comfortable soaking experience.

Key Benefits:

• Increases calcium hardness in spa and hot tub water

• Helps prevent corrosion and damage to spa surfaces and equipment

• Reduces cloudiness caused by low calcium levels

• Promotes clear, balanced water for an enjoyable spa experience

• Minimizes skin and eye irritation for bathers
