The limewater method is often used in marine aquariums to increase calcium and carbonate hardness levels in the water. This helps stabilize the pH value and promotes the growth of corals and other organisms.

Application:

• Add 1 tablespoon (7 - 10 g) of calcium hydroxide to 10 liters of osmotic water, stir and leave in a well-sealed container for several hours.
• The resulting clear liquid is limewater, which can be gradually added to the aquarium.

Dosage tip: To add the limewater solution to the aquarium, use a limewater reactor or a dosing pump.
