FritzPro Calcium Chloride is a professional-grade, pure calcium supplement designed for reef and marine tanks. Its anhydrous formula delivers targeted calcium increases without introducing unwanted contaminants.

Key Benefits

• Highly effective dosing—each 1 g per 10 US gal raises calcium by ~10 ppm
• Clean, contaminant-free powder—phosphate- and ammonia-free
• Supports coral skeletons, calcifying algae, snails, and clams
• Compatible with two-part dosing systems and other FritzPro supplements

Directions & Dosage

• Measure current calcium level before dosing
• Add 1 g per 10 US gal to raise Ca by ~10 ppm (≈5.2 g per 10 gal = +50 ppm)
• Dissolve in RO/DI or distilled water before adding to sump or high-flow area
• Split doses into thirds or halves; wait 24 hrs between for large increases
• Do not increase calcium by more than 20 ppm per day
• Wear gloves—solution heats during dissolution; avoid skin/eye contact
• Allow cloudiness to clear before retesting, then adjust alkalinity or magnesium if needed
