Seachem Laboratories Reef Kalkwasser Supplement 1ea/8.8 oz.

$13.99

Reef Kalkwasseris 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 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 Builderor Reef Carbonate(do not mix these directly with a kalkwasser solution).

Very pure calcium hydroxide
Ideal for increasing calcium in top-off water
Increases pH with no impact on carbonate alkalinity
