Tropic Marin Bio-Calcium Original Balling Liquid Set (1000ml)

The Tropic Marin® Original Balling Liquid Set is a professional-grade 3-part dosing system designed to deliver balanced supplementation of calcium, alkalinity, and essential trace elements in reef aquariums. Based on the well-established Balling method, this system goes beyond traditional 2-part solutions by maintaining long-term ionic balance in your system—critical for the health and stability of marine life.

The set includes three precisely formulated liquid components:

• Part A – Calcium chloride dihydrate (20,000 ppm Ca) to support skeletal growth and biological functions in corals and invertebrates.

• Part B – A carefully balanced mix of sodium carbonate and bicarbonate (2,800 °dH/L) to stabilize alkalinity and buffer pH levels.

• Part C – Sodium chloride-free sea salt enriched with magnesium (~3,350 ppm) and potassium (~980 ppm) to replace trace elements typically depleted through regular calcium and alkalinity dosing. This ensures ionic consistency without the unwanted accumulation of sodium chloride.
