Description: Seachem Reef Kalkwasser 500g. is a pure calcium Hydroxide with unsurpassed purity and solubility characteristics. This calcium Hydroxide meets or exceeds the purity of competing brands designated for reef use. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that are used in an automated dosing system that replaces evaporated water. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, it's capacity to perform these functions is dependent on evaporation rate and CO2 concentration. If these two factors are insufficient you can provide additional calcium with Reef Advantage Calcium, Reef Complete, or Reef Calcium, and carbonate alkalinity with Reef Builder or Reef Carbonate (do not mix these directly with a Kalkwasser solution). Reef Kalkwasser can also precipitate phosphates and impurities from make-up water, while maintaining a high pH which is important for maintaining high calcification rates and for oxidizing various organics in reef aquaria. A 500g bottle makes 650L (166 gallons) of kalkwasser solution.
