Reef Kalkwasser is a pure calcium
hydroxide with unsurpassed purity and solubility characteristics. Calcium
hydroxide is used to prepare lime water (kalkwasser) solutions that are used in
an automated dosing system that replaces evaporated water. 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 the 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 the makeup water while maintaining a high pH
which is important for proper calcification rates and for oxidizing various
organics in reef aquaria.
Never add this product directly to the aquarium. Add 1 teaspoon to 1 gallon of
water and mix to dissolve. If using pure water, a fully saturated solution is
prepared by adding 2 teaspoons to 1 gallon. Drip this solution into aquarium.
Monitor pH and carbonate alkalinity. Adjust rate of addition to maintain a
stable pH (8.3-8.4). Always use the clear supernatant (top solution) only and do
not allow undissolved material to enter the aquarium.
