Seachem Reef Kalkwasser is a high-purity calcium hydroxide powder formulated for preparing limewater (kalkwasser) solutions to help maintain calcium at natural seawater levels in reef aquariums. It supports coral growth by directly increasing calcium and indirectly boosting carbonate alkalinity, making it a trusted choice for experienced reef keepers. The product dissolves quickly, offering excellent solubility and consistent performance when used in top-off water.
