Seachem Reef Kalkwasser 250g
Directions for use:
Never add this product directly to the tank. Add 3 g (1 teaspoon) to 1 gallon of water and mix to dissolve. If using pure water, a fully saturated solution is prepared by adding 6 g (2 teaspoons) to 4 L 1 gallon. Drip this solution into tank. Monitor pH and carbonate alkalinity. Adjust rate of addition to maintain a stable pH (8.3–8.4). HINTS:
Adding 1 gallon of a saturated kalkwasser solution to 40 gallons will raise calcium by 24 mg/L. Always use the clear supernatant (top solution) only and do not allow undissolved material to enter the aquarium. Keep this container tightly closed when not in use and minimize solution/air contact to avoid calcium carbonate formation/precipitation.
