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 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).
While 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.
