CONCENTRATED BLEND: Seachem's Reef Advantage Calcium is a non-caustic optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater.
CORAL GROWTH: Calcium is included in this blend and is essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral growth.
MAINTAIN CALCIUM: In addition to calcium, Reef Advantage Calcium also includes magnesium and strontium in amounts proportionate to typical utilization ratios. This allows one to maintain these two elements while also maintaining calcium.
USE: Reef Advantage Calcium does not have a caustic pH and will not deplete magnesium. When used as directed, it will not deplete alkalinity or carbonates.
DIRECTIONS: Use 5 g(1 level teaspoon) per 150 L(40 US gallons) twice a week. For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least 250 mL(1 cup) of freshwater. Check calcium every 2 weeks and adjust the amount or frequency accordingly.
