DRAK - Remineralizing Salts for Your Aquarium!

For conditioning demineralized water from a reverse osmosis unit or a cation exchanger, DRAK offers various remineralizing salts that have become firmly established in the aquarium hobby. Very soft tap water or rainwater can also be enriched with important minerals using these high-quality, very pure products. You can choose from various salt blends. Duradrakon raises both the general hardness (GH) and the carbonate hardness (KH). With Duradrakon GH-Plus and Duradrakon KH-Plus, these parameters can be adjusted independently of each other.
