It contains a minimum of 250,000 ppm of magnesium per kilogram.
Available in sizes 250ml, 500ml, 1000ml and 3000ml.
Before using the product measure the magnesium concentration in the aquarium using a proper test kit. Add up to 15 g per 100 litre until the magnesium reaches the desired level. 1g Pure Magnesium ( 1 ml Pure Magnesium = -11 gr ) causes a 25 ppm increase in 100 litre. When the required levels are reached then periodic tests should be performed to determine consumption amounts and the water should be topped up as required on a daily or weekly basis. The suggested quantity should be dissolved in freshwater and added to the SUMP. If the daily consumption rate is over 5 ppm then it is recommended that addition be done using the balling method through the dosage pump.
