Seachem Reef Calcium

Seachem Reef Calcium

Reef Calcium™ is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Additionally, polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system.

Polygluconate complexation confers several benefits: it increases the bioavailability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion.

Reef Calcium™ utilizes a chained organic calcium rather than an ionic calcium. When a coral absorbs a molecule into its tissue, it uses the same amount of energy regardless of molecular size. However, charged molecules require more energy. When an uncharged molecule of Reef Calcium™ is absorbed, the coral acquires multiple calcium atoms as well as an easily metabolized carbohydrate with less energy expended than it uses for ionic calcium uptake. Therefore, at lower calcium levels, corals can still take in as much calcium through our organic chains as they would at much higher levels of ionic calcium.

Key Benefits

• Liquid organic calcium source
• Maintains calcium and accelerates coral growth
• Concentrated (50,000 mg/L)
• Directions

Directions and Care

Add 1 capful (5 mL) per 80 L (20 US gallons) twice a week. You can increase the amount or frequency based on growth response but do not exceed 3 capfuls per 80 L (20 gallons) per day. Each capful will raise calcium by about 3 mg/L.

Notes: Use the Reef Status™: Calcium test kit to measure calcium. It is not necessary to exceed 380 mg/L total calcium when using this product. Color and clarity may vary between lots.

Storage and Safety

Keep the container tightly closed in a cool, dry place. Keep out of reach of children and use only as directed on the product label.
