DRAK - aquaristics products from own research and production!
The man behind DRAK is the aquaristics expert and chemist Dr. Andreas Kremser. As a manufacturer of products for water care, DRAK also offers aquarium fertilizers and epsom salts for water treatment in aquariums. Ferrdrakon is recommended as a classic iron complete fertilizer, while KramerDrak is more suitable for heavily planted aquariums with correspondingly strong lighting. Various macronutrients are also available as single component fertilizers.
A popular hardening salt is Duradrakon, for example, which specifically increases both the carbonate and total hardness. DRAK also offers useful pH buffer solutions for calibrating pH electrodes and long-term fertilizers in solid form.
