Grotech Magnesium Pro Instant 1000g

Immediately soluble Magnesium

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.

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.

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

Seachem reef advantage magnesium 600g

Reef Advantage Magnesium is a concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water. Reef Advantage Magnesium contains no ammonia! This is a common contaminant in every liquid magnesium supplement on the market.

Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels. Magnesium depletion is commonly associated with the use of kalkwasser.
