Reef Calcium 250 ml Seachem – organic polygluconate calcium for reef aquariums

Reef Calcium is a biodisposable polygluconate calcium supplement designed to maintain calcium at levels suitable for a reef aquarium without altering the pH. Its formulation contains no nitrogen or phosphorus.

Main Features

Type: organic liquid calcium supplement.

Volume: 250 ml.

Form: polygluconate calcium.

Concentration: 50,000 mg/L.

Principles of Polygluconate Formulation

Calcium is provided in organic form, as a polygluconate complex. This complexation increases calcium bioavailability, provides a source of associated metabolic energy, and limits calcium precipitation.

Reef Calcium uses a non-ionic complexed form rather than strictly ionic calcium. This allows calcifying organisms to absorb calcium with reduced energy cost, which can promote growth maintenance even when calcium levels are lower than with a purely ionic approach.

Usage in Calcium Management

Reef Calcium is intended for calcium maintenance. In cases of severely depleted calcium, a water change or the use of an ionic calcium supplement is recommended to restore the level, after which Reef Calcium can be used to support maintenance and growth.

It can be used alone for calcium maintenance and can be used in conjunction with an ionic calcium supplement such as Reef Complete or Reef Advantage Calcium.

Usage Instructions

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

The amount or frequency can be increased based on growth response, not to exceed 15 ml per 80 L per day.

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

Notes and Parameter Monitoring

Monitor calcium using an appropriate test. It is not necessary to exceed 380 mg/L of total calcium when using this product.

The color and clarity of the product may vary between batches.

Important Considerations

The recommended calcium level is between 380 and 420 mg/L, with alkalinity between 3 and 6 meq/L.

Significant adjustments should be made gradually to avoid shocking corals and invertebrates.

Excess calcium can increase carbonate alkalinity loss.

Do not mix directly with a carbonate supplement. It is advised to space additions by at least 30 minutes.

Frequently Asked Questions

Algae Risk and Organic Carbon Presence

Reef Calcium is formulated based on polygluconate. Polygluconate is not equivalent to glucose. Usage should remain within recommended dosages, as with any organic source used in aquariums, to avoid excessive input beyond what the system can assimilate.

Compatibility with Calcium Tests

Reef Calcium is a complexed calcium. Most market calcium tests can measure calcium with this type of supplement.

Presence of Crystals in the Bottle

The presence of crystals around the edge of the bottle can occur and is considered normal. Shaking typically allows them to dissolve back into solution.

Differences between Reef Calcium, Reef Advantage Calcium, and Reef Complete

Reef Advantage Calcium and Reef Complete are ionic calcium supplements intended to increase calcium levels. Reef Complete is the liquid version, while Reef Advantage Calcium is the powder version.

Reef Calcium is an organic supplement primarily intended for calcium maintenance and growth support when used alone or in addition to ionic calcium.

Package Contents

Reef Calcium is a technical supplement intended for reef aquariums. Regular monitoring of calcium and alkalinity is essential to ensure system stability.
