PH stabiliser nt labs

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.
