||Pure calcium hydroxide with unsurpassed purity and solubility
||Increases or maintains calcium concentration at natural seawater levels
||Ideal way to maintain crucial calcium levels in reef aquariums
Ultra fine, easy-to-mix, powdered calcium hydroxide for reliable calcium supplementation. Produces a kalkwasser solution that maintains calcium concentrations at natural seawater levels in your reef aquarium. Contains no phosphates. Use with a doser to dispense prepared kalkwasser. 500 grams makes 650 L. of kalkwasser solution.
Never add this product directly into your aquarium.
Add 3 g (1 teaspoon) to 4 L (approximately 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 (approximately 1 gallon). Drip this solution into aquarium with a doser. Monitor pH and carbonate alkalinity. Adjust rate of addition to maintain a stable pH (8.3-8.4).
Tip: Adding 4 L (approximately 1 gallon) of a saturated kalkwasser solution to 150 L (approximately 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.
Avoid contact or breathing dust. Do not eat or get in eyes. In case of contact, flush area with water for 5-10 minutes. In case of eye contact, wash eyes with water immediately (5-10 minutes) and seek medical attention.
