Description
This hardening salt mixture is suitable only for Aquarium water with adequate free CO2 (preferred is when the CO2 is produced by a controlled CO2 system) and where there is a pH-value wide under 7 (preferred RO - as well as DM-water), because otherwise some components only disperse slowly or not at all!
Pure reverse osmosis-water is not suitable, except for a few special cases, (pure circulation-pools, black water biotope), for direct application in the aquarium. The few available mineral substances that it still contains are too quickly used-up. To supply fish and plants it is therefore sensible and correct, that the water used should be hardened to a total hardness / carbonate hardness value of 1 - 3 ° dH. Those that do not wish to do this by blending together with drinking water or that are not in a position to do it, (e.g. the origin water would be too polluted!), will need a hardening salt mixture, that supplies the water with a pre-defined dosage of mineral substances.
Usage
According to the situation, whether one prefers to increase the total hardness or the carbonate hardness, are the dosages (slightly) different:
To increase about 1 °d TH you will need approx. 2.8 g Duradrakon / 100 l water.
To increase about 1 °d CH you will need approx. 3.6 g Duradrakon / 100 l water.
With a dosage of approx. 3.6 g Duradrakon per 100 l water, the following amounts of important ions are added:
22.3 mg/l hydrogencarbonate, 6.2 mg/l calcium, 5.3 mg/l sulfate, 3.6 mg/l chloride, 2.0 mg/l sodium, 1.9 mg/l magnesium, 0.8 mg/l potassium, trace elements

Präzise Aufhärtung von Umkehrosmosewasser
Härte mit 21,6 Gramm Duradrakon verlässlich 300 Liter Umkehrosmosewasser von KH 0 auf KH 2 auf. Das Pulver kommt bei mir in einen Becher und wird mit stark kohlensäurehaltigem Mineralwasser zu 90% aufgelöst und dann ins Umkehrosmosewasser gekippt. Eine Pumpe befördert es ins Aquarium. Ich nehme an dass Calcium sich am schlechtesten löst, daher bleibt eine Schicht am Boden liegen, die ich aber am Ende durch Aufwirbeln mit der Hand dann aber auch durch die Pumpe und damit ins Aquarium bekomme. Dort löst sich der Rest dann auch nach einer Stunde oder so komplett auf.
