In the marine water aquarium, great quantities of Calcium and Magnesium are required, in order to achieve an optimum growth of corals and red calc algaes.

1 measuring spoon (abt. 10g) results in an increase of the Magnesium contents by abt. 11mg/l per 100 liter aquarium water, without shifting of the ion balance.

In case of larger deviations, the quantity should be increased over a period of numerous days via the refill water. In case of minor quantities, please dose directly into the filter bassin at a well- floated area.

For a constant Magnesium level in the aquarium, we recommend to admix Magnesium pro in the Calcium reactor.
When using Magnesium pro instant in the aquarium, please check regularly the Calcium contents of the aquarium water.
The optimum value is at abt. 1330mg/l.
