Preis Magnesium Heptahydrate 450Gr

Preis Magnesium Sulfate Heptahydrate – Magnesium Supply in Seawater

Role of Magnesium in Reef Aquariums

After sodium chloride, magnesium is the most abundant element in natural seawater. Its target concentration is about 1350 mg/L. In reef aquariums, deficits may occur and require correction to preserve the chemical stability of the system.

Usage Principle

To correctly increase the magnesium level, it is necessary to combine Preis magnesium chloride hexahydrate and Preis magnesium sulfate heptahydrate. This combination maintains a balanced ratio between chloride and sulfate ions.

The required ratio to obtain 1 g of magnesium is as follows:

7.58 g of magnesium chloride hexahydrate
0.95 g of magnesium sulfate heptahydrate

Method of Addition

The salts must be precisely weighed using a high-resolution scale, dissolved in osmosis water, and then gradually added to the aquarium over several days.

Avoid too rapid an increase in magnesium. It is recommended to regularly check the concentration using an appropriate test.

Preparation of Solutions

Example of a 5% solution:

In 700 ml of water, dissolve:
380 g of magnesium chloride
48 g of magnesium sulfate
Then fill up with water to obtain 1000 ml.

This solution can be gradually added over several days according to the tank's needs.
