Seachem Reef Advantage Calcium – 500g

Product details

Seachem Reef Advantage Calcium – 500g (313) is a concentrated powder source of ionic calcium for marine aquariums. It is designed to help restore and maintain calcium levels found in natural seawater—an essential building block for coral growth. When calcium (and related balance of carbonates) becomes deficient, coral growth can slow or stop and overall coral health may decline. This product also includes magnesium and strontium in proportions intended to match typical aquarium utilization, supporting a more balanced approach than calcium-only supplements.

Features:

• Concentrated ionic calcium formulated to support natural seawater calcium levels
• Includes magnesium and strontium in amounts proportionate to typical utilization ratios (Ca:Mg:Sr = 100:5:0.1)
• Optimized to be non-caustic, with a pH range of about 8.3–8.6
• Designed to be added directly to the aquarium as directed by the manufacturer
• Helps maintain magnesium and strontium while replenishing calcium
• Unlike limewater (kalkwasser), it is described as not being caustic in pH and not as depleting magnesium
