Reef Calcium Seachem 4 L – Organic Calcium for Reef Aquarium

Reef Calcium is a polygluconate calcium concentrated at 50,000 mg/L, designed to maintain stable calcium levels in reef aquariums. Unlike traditional ionic forms, this organic calcium is easily assimilated by corals while requiring less metabolic energy for absorption.

Its formulation does not alter pH and contains neither nitrogen nor phosphorus, preventing undesirable algae growth in a properly maintained reef system.

Principle of Polygluconate Calcium

The calcium present in Reef Calcium is bound to an organic polygluconate chain. This complexation improves the bioavailability of calcium, limits precipitation phenomena, and simultaneously provides a source of metabolic carbon easily usable by corals.

Thanks to this uncharged form, calcium can be absorbed more efficiently by coral tissues, even when total calcium concentrations are moderate.

Main Features

Liquid organic calcium with high bioavailability.

Concentration: 50,000 mg/L.

No impact on pH.

No nitrate or phosphate.

Recommended Use

Reef Calcium is primarily intended for maintaining calcium levels and optimizing coral growth. In case of significant deficiency, it is recommended to use an ionic calcium supplement or perform a water change before resuming maintenance with Reef Calcium.

It can be used alone or in conjunction with an ionic calcium such as Reef Complete or Reef Advantage Calcium to maximize coral growth.

Dosage

Add 5 ml for 80 L of water, twice a week.

The amount or frequency can be adjusted according to coral growth response, not exceeding 15 ml for 80 L per day.

Each 5 ml dose for 80 L increases calcium by approximately 3 mg/L.

Recommendations and Precautions

The recommended calcium level in a reef aquarium is between 380 and 420 mg/L, with alkalinity between 3 and 6 meq/L (8 to 17 dKH).

Significant adjustments should be made gradually to avoid any imbalance or stress for the corals.

An excess of calcium can lead to increased consumption of carbonate alkalinity. It is not recommended to directly mix Reef Calcium with a carbonate supplement.

Packaging

Volume: 4 liters.

Other formats available: 100 ml, 250 ml, 500 ml.

Reef Calcium Seachem is designed to ensure stable and effective calcium maintenance in reef aquariums, while supporting sustainable coral growth.
