Seachem 's Kalkwasser is a pure calcium hydroxide with unmatched purity and solubility characteristics . Calcium hydroxide is used to prepare lime water solutions (kalkwasser) which will maintain calcium concentrations at natural seawater levels. Ideal for increasing calcium in make-up water. Raises pH without impacting carbonate alkalinity.
Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, its ability to perform these functions depends on the rate of evaporation and the concentration of CO2. 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 them directly with a solution of kalkwasser).
Never add this product directly to the tank. Add 3 g (1 teaspoon) to 4 L (1 US gallon) of water and stir to dissolve. If using pure water, a fully saturated solution is prepared by adding 6 g (2 teaspoons) to 4 L (1 US gallon). Drip this solution into the tank. Monitor pH and carbonate alkalinity. Adjust the addition rate to maintain a stable pH (8.3–8.4).
