Experience superior calcium maintenance for your marine aquarium with this high-purity calcium hydroxide product designed to prepare effective limewater (kalkwasser) solutions. Its exceptional purity and solubility ensure that calcium concentrations remain consistent with natural seawater levels, supporting healthy coral growth and overall reef vitality. By maintaining calcium directly and carbonate alkalinity indirectly, this solution helps stabilize essential water chemistry parameters crucial for thriving saltwater environments.
Optimal performance depends on factors such as evaporation rate and CO2 concentration; if these are insufficient, additional calcium and carbonate alkalinity supplements can be used to complement this treatment. For best results, always prepare the solution by dissolving 3 g (1 teaspoon) in 4 L (1 gallon) of water, or create a fully saturated solution with 6 g (2 teaspoons) per 4 L. Administer the clear supernatant portion via drip into your aquarium, carefully monitoring pH and carbonate alkalinity to maintain a stable pH between 8.3 and 8.4.
Adding 4 L of a saturated kalkwasser solution to 150 L of aquarium water can raise calcium levels by approximately 24 mg/L, contributing to a balanced and supportive environment for marine life. To prevent calcium carbonate precipitation, keep the container tightly sealed when not in use and minimize air exposure. Avoid introducing undissolved material into the tank to maintain water clarity and quality.
Safety precautions are essential: avoid inhaling dust or allowing contact with skin and eyes. In case of exposure, rinse thoroughly with water for 5–10 minutes and seek medical attention if necessary. This economical and effective limewater mix is ideal for aquarists dedicated to maintaining precise ionic concentrations, though beginners or those with limited time may opt for alternative methods.
