Reef Kalkwasser Seachem is a very high purity calcium hydroxide intended for the preparation of limewater solutions. It helps maintain calcium levels close to those of natural seawater while contributing to pH stability in reef aquariums.
SEACHEM
Type: very pure calcium hydroxide.
Usage: preparation of kalkwasser solution.
Function: maintenance of calcium and stabilization of pH.
Impact: increases pH without directly affecting carbonate alkalinity.
Compatibility: reef aquarium.
Calcium hydroxide is used to prepare a limewater solution that directly maintains calcium and indirectly alkalinity. The effectiveness of the process depends on the rate of evaporation and the CO2 concentration of the system.
If these parameters are insufficient, additional calcium or alkalinity supplementation may be necessary using dedicated supplements, without ever mixing them directly with a kalkwasser solution.
Reef Kalkwasser is an economical and effective solution, but it requires diligence, monitoring, and a good understanding of tank operation. Aquarists seeking a simpler method may prefer other supplementation systems.
250 g, 500 g, 1 kg, 2 kg.
Never add Reef Kalkwasser directly into the aquarium.
Add 3 g (about 1 teaspoon) into 4 L of osmosis water and mix to dissolve.
For a fully saturated solution with pure water, add 6 g (2 teaspoons) per 4 L of water.
Administer the solution by drip into the aquarium.
Monitor the pH and carbonate alkalinity and adjust the addition rate to maintain a stable pH between 8.3 and 8.4.
The addition of 4 L of a saturated solution into 150 L of water increases calcium by about 24 mg/L.
Use only the clear solution above the sediment and avoid introducing any undissolved material into the aquarium.
Keep the container tightly closed and limit air contact to prevent the formation and precipitation of calcium carbonate.
The sediments deposited at the bottom of the container after preparation are generally not reusable. Over time, calcium hydroxide reacts with CO2 to form calcium carbonate, which precipitates and does not redissolve.
