GROTECH - Magnesium Pro Liquid - 1000ml - Magnesium for saltwater aquarium

For a rapid increase in Magnesium levels in the event of a deficiency, we recommend Magnesium pro liquid.

This allows a rapid and safe increase in Magnesium levels. 1 Liter of Magnesium pro liquid contains 50,000 mg of Magnesium = 1 ml of Magnesium pro liquid contains 50 mg of Magnesium

Here is an example for the calculation of Magnesium Pro Liquid:
First you need to measure the actual value of magnesium in the aquarium.

You have 1200mg/l magnesium in the aquarium and you want to increase to 1300mg/l.
You have a 500 liter aquarium. The mg value of magnesium pro liquid is 50,000 mg/litre.

The desired magnesium value - the actual value = deficit in mg/litre
1300 mg/l - 1200 mg/l = 100 mg/ liter

Deficiency in mg/litre x aquarium content in liters = magnesium deficit
100 mg/ liter x 500 liters = 50,000 mg

Magnesium deficiency: Magnesium Pro Liquid 50,000 mg/ liter = the necessary supplement in liters
50,000 mg: 50,000 mg/l = 1 liter
