Over time the carbonate hardness (KH) level in your aquarium will drop. This reduces the pH and can lead to sudden fluctuations. NT Labs Aquarium KH Up, pH Stabiliser is both phosphate and nitrate free.
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. Using the NT Labs Stabiliser will help you achieve this by safely increasing the KH level.
