REEF MAGNESIUM is a liquid source of magnesium. The formulation has been studied and adapted in our Research and Development laboratory to be perfectly assimilable by corals at the times of greatest demand and is in such a form as to be easily assimilated without requiring too much power. Very low levels of magnesium can cause alterations in the pH, KH value and the inability to maintain the calcium level. Seawater, and consequently that of aquariums, is rich in calcium carbonate as vegetal and animal organisms, sessile and floating, form calcium carbonate using bicarbonate ions and calcium ions present in water, according to the following process of formation of the carbonates by precipitation:

Ca²+ + 2HCO³- ↔ CaCO³ + CO² +H²O:

CaCO³ = calcium carbonate

CO² = carbon dioxide

H²O = water

Ca²+ = calcium ions

HCO³- = bicarbonate ions

At normal temperatures and pressures salt, CaCO³, is essentially insoluble in water but the solubility increases with pressure and decreases with temperature; calcium carbonate dissolves and dissociates into Ca²+ and CO³²-. In the absence of magnesium, the level of calcium and carbonates would be much higher than the value that the water is able to maintain in equilibrium, causing alterations to the ideal values of the aquarium water.

The presence of Magnesium in the water promotes the following chemical reaction:

Ca²+ + Mg²+ + CO³²- → CaMg[CO³]²

CO³² = Carbonate ion

Ca²+ = calcium ions

CaMg[CO³]² = double carbonate of magnesium and calcium

The magnesium in this reaction is fundamental because, when the calcium carbonate begins to precipitate, the magnesium binds to it, preventing any further deposit, blocking its precipitation and creating double carbonate of magnesium and calcium, easily soluble and assimilable. For this reason it is necessary to maintain correct values of magnesium, calcium and KH in order to avoid the production of precipitation and sudden changes in the values of the aquarium water.

Available size:

250 ml - Item code RMA

Shake the bottle before use, pour 10 ml (= 1 cap full) for every 100 litres of water directly into the aquarium. Treatment on average is once a week. Increase treatment (every 4-5 days) if there are numerous organisms in the aquarium. It is highly recommended to keep the product out of reach of children.
