Reef Kalkwasser ™ - 2kg - SEACHEM
- Very pure calcium hydroxide
- Ideal for increasing calcium in top-off water
- Raises pH without impacting carbonate alkalinity
Overview
Reef Kalkwasser ™ is pure calcium hydroxide with unmatched purity and solubility characteristics. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that will maintain calcium concentrations at natural seawater levels. Kalkwasser solutions directly maintain calcium and indirectly carbonate alkalinity. However, its ability to perform these functions depends on the evaporation rate and CO2 concentration. If these two factors are insufficient, you can provide additional calcium with Reef Advantage Calcium ™, Reef Complete ™, or Reef Calcium ™, and carbonate alkalinity with Reef Builder ™ or Reef Carbonate ™ (do not mix them directly with a kalkwasser solution).
Although Reef Kalkwasser ™ is a high purity and economical limewater mix, beginners or those who do not have as much time to dedicate to their system may prefer to use other, less involved methods to maintain proper ionic concentration levels.
Sizes: 250g, 500g, 1kg, 2kg
Instructions
Never add this product directly to the tank. Add 3g (1 teaspoon) to 4L (1 US gallon) of water and mix to dissolve.
If using pure water, a fully saturated solution is prepared by adding 6g (2 teaspoons) to 4L (1 US gallon).
Drip this solution into the tank.
Monitor pH and carbonate alkalinity.
Adjust the addition rate to maintain a stable pH (8.3–8.4).
Notes: Adding 4L (1 US gallon) of a saturated kalkwasser solution to 150L (40 US gallons) will increase calcium by 24 mg/L.
Always use only the clear supernatant (upper solution) 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 prevent the formation/precipitation of calcium carbonate.
FAQ
After mixing a limewater solution, are the sediments left at the bottom of the container reusable until fully dissolved or should they be discarded?
It is very likely that the excess calcium hydroxide (kalkwasser or limewater) that has settled at the bottom will not dissolve and should be discarded. The longer it remains, the more likely the hydroxide is to convert CO2 in the water into carbonate. This carbonate will form a precipitate with calcium (calcium carbonate) and will not dissolve.
