Raises Calcium Hardness | Prevents Corrosion & Surface Damage | Easy-to-Use Granules

SpaGuard Calcium Hardness Increaser is designed to boost the calcium hardness level in your spa or hot tub, preventing equipment corrosion, surface etching, and foam caused by soft water. Proper calcium levels protect heaters, pumps, and spa surfaces—ensuring longer-lasting equipment and sparkling clear water.

• 🔧 Prevents Corrosion & Etching: Guards against damage to spa surfaces and vital equipment.
• 🧪 Easy Dosing: 1 tablespoon (0.5 oz) per 100 gallons increases hardness ~25 ppm.
• 💧 Simple Application: Evenly broadcast granules into spa water with the circulation running.
• ⏲️ Fast Acting: Re-test water after 4 hours and rebalance if necessary.
• ♻️ Use As Needed: Especially important after draining/refilling or when using softened water.

Directions for Use:

• Test spa water regularly to ensure calcium hardness is within the recommended range (150–250 ppm).
• If below range, add product as directed above.
• Allow spa to circulate for at least 4 hours, then retest and readjust if needed.
• Avoid exceeding 400 ppm to prevent scale formation.

Why Proper Calcium Matters: Balanced calcium hardness helps prevent foaming, keeps water crystal clear, and reduces overall chemical demand. It’s essential for new fills and ongoing spa maintenance.

Always follow label instructions. SpaGuard is a trusted leader in spa water care.
