Mix 1 measure (~ 7 g) of calcium hydroxide in 10 liters of demineralized water and let it sit overnight in an airtight container. It is possible to replace the evaporated water from the aquarium by dripping the clear liquid. Do not pour it all at once to avoid a sharp increase in the pH value. Warning: Causes burns! In case of contact with eyes, rinse thoroughly with water and consult a doctor. Keep out of reach of children!
