Seachem Reef Kalkwasser 250g

Seachem Reef Kalkwasser is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. It will provide supplemental calcium to reef inhabitants, as well as allowing for lush growth of purple, pink and green calcareous algaes. Seachem Reef Kalkwasser also helps to maintain the pH and alkalinity of your aquarium.

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.
