When to use?
Over time the carbonate hardness (KH) level in your aquarium will drop. This reduces the pH and can lead to sudden fluctuations.

Certain species of fish require a higher KH level and in turn a high pH so it is important to regularly maintain the correct KH level.

How to use:

• Use 6g (1 level teaspoon) for every 100 litres of aquarium water to increase the KH by 2odKH.
• Dissolve the required amount in a small volume of aquarium water before adding to your aquarium.
• Do not increase the KH of your aquarium by more than 2odKH every 24 hours.
