Inhabitants of reef tanks require calcium for the growth of their skeletons & shells, consuming calcium and carbonate hardness from the water in large quantities, which requires replenishment.
ROWA®kalk is an extremely pure form of calcium hydroxide, which dissolves in water to produce Kalkwasser, a solution which reacts further within the aquarium to produce calcium, carbonate and bicarbonate ions. The fresh solution can be used to replace part or all of the daily evaporated water into your aquarium, depending on demand, and will also increase the pH value of your water.
Stir the ROWA®kalk vigorously by the spoonful into reverse osmosis water in a covered ideally transparent container. The water will turn milky and must settle and clear before use. Do not add the settled layer to the Aquarium and only make up as much kalkwasser as required, as the solution reacts with CO2 in the air and loses strength.
The clear solution should be added to the Aquarium very slowly, drop by drop, into an area of high flow throughout the day, using either a peristaltic pump or by gravity drip feed (important as Kalkwasser has a high pH of 12,4).
Dosage: 1 - 4 teaspoons of ROWA®kalk per 5 Liters, dependent on coral stocking and type. Test Aquarium alkalinity regularly and adjust as required.
