Lime water / calcium hydroxide for the production of lime water The lime water method is often used in marine aquariums to increase the calcium and carbonate hardness content in the water. This helps to stabilise the pH value and promote the growth of corals and other calcifying organisms. Application: Add 1 tablespoon (7 - 10 g) of calcium hydroxide to 10 litres of osmosis water, stir and leave to settle in a sealed container for several hours. The resulting clear liquid is the lime water, which can be added to the aquarium drop by drop. Dosing tip: Use a lime water reactor or a dosing pump to add the lime water solution to the aquarium. Hazard statements: H315 Causes skin irritation. H318 Causes serious eye damage. H335 May cause respiratory irritation. Ingredient: Calcium hydroxide
