Kalkwasser - Krakking Korals

Kalkwasser is one of the easiest and low cost method to keep calcium and alkalinity at desired levels in your reef tank.

Instructions: Add 1.6g of Calcium Hydroxide to 1L of RODI water and gently stir for 60 seconds to achieve maximum saturation.

Adding more will not achieve a stronger concentration. It is only necessary to stir again if more RO water is added.
