The water conditioner Aquadur by JBL is a hardening salt mixture suitable for every soft water, like soft tap water, spring water and osmosis water. Hereby, ideal water values for invertebrates, reptiles and fish can be set in every freshwater aquarium. With Aquadur a professional increase of the carbonate hardness and stabilisation of the pH-value is achieved and therefore an acid drop is prevented. At the same time the fish are protected against mineral deficiencies by an optimal mineral salt mixture in this biotope-compatible environment. This mineral mixture is based on the ion distribution of many tropical waters, in which most inhabitants of aquaria are feeling well. Furthermore, the total hardness can be easily adjusted with the enclosed measuring spoon until the desired degree of hardness is reached.

One level measure spoon (ca. 18,75 g) increases up to 2,5° d CH and 3,2 d TH in 100 l water. The conductance will be increased by approx. 210 µS.

This product is hygroscopic, which is why it should always be stored at a dry place and well sealed. Otherwise, it may reacts with the ambient humidity and become hard. However, this does not spoil the product, but makes it harder to remove from the can and it dissolves more slowly in water.

It is recommended for everyone who wants to increase the hardness of the water without changing the Ph. It dissolves completely, leaving no trace of dust.
