Product details
Seachem Reef Advantage Calcium 250g (316) is an aquarium additive designed to restore and help maintain calcium levels in reef aquariums. It uses an ionic (powder) form of calcium, intended to support coral growth by keeping calcium available for carbonate-related needs. When calcium becomes deficient, coral growth can stall and coral health may decline, so this product is commonly used to correct and maintain calcium as part of broader reef element management.
Features:
- Provides concentrated, powder ionic calcium for use in marine reef systems
- Non-caustic formulation with a pH range of 8.3–8.6
- Includes magnesium and strontium in proportions intended to match typical utilization ratios (Ca:Mg:Sr = 100:5:0.1)
- Can be added directly to the aquarium
- Designed to restore and maintain calcium to levels found in natural seawater
- When used as directed, it is stated not to deplete alkalinity
