Product details
Seachem Reef Fusion 1 1L (1207) is a two-part reef aquarium additive designed to supply calcium for saltwater systems. It is the “calcium” half of the Reef Fusion™ foundation system, formulated to help maintain essential reef water parameters when used alongside its corresponding alkalinity product (Reef Fusion 2™). In practice, it’s used as part of a calcium/alkalinity routine to support reef aquarium stability rather than as a standalone supplement.
Features:
- Provides 100,000 mg/L of ionic calcium for reef aquarium calcium needs
- Intended to be used as part of the Reef Fusion™ two-part system to maintain calcium and alkalinity levels
- Uses a simple 1:1 ratio pairing approach with Reef Fusion 2™
- Includes additional supporting trace elements: magnesium, strontium, boron, iron, manganese, and molybdenum
