Directions
Add 1 level measuring spoon of Kalkwasser to 5 litres of RO/DI water, stirring lightly for 3 minutes. Let stand for 5 minutes, then slowly drip into a high-flow area of the aquarium. Avoid adding any undissolved residue to the tank. Regularly test alkalinity to determine correct dosing levels. Do not add Kalkwasser powder directly to the aquarium.
