Seachem Reef Kalkwasser 250g

Seachem Reef Kalkwasser is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that will maintain calcium concentrations at natural seawater levels. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, its capacity to perform these functions is dependent on evaporation rate and CO2concentration. If these two factors are insufficient you can provide additional calcium with Seachem Reef Advantage Calcium, Seachem Reef Complete, or Seachem Calcium and carbonate alkalinity with Seachem Reef Builder or Seachem Reef Carbonate (do not mix these directly with a kalkwasser solution).

While Seachem Reef Kalkwasser is a high purity and economical limewater mix, the beginner, or someone with not as much time to devote to their system, may prefer to use other less involved methods for maintaining proper ionic concentration levels.
