NT Labs Aqua PH Stabiliser KH UP180g

NT Labs KH Up  pH Stabiliser is a simple, effective water treatment designed to raise carbonate hardness (KH) and stabilise pH in freshwater aquariums. Over time the KH level in an aquarium will naturally fall, which can drag pH down and cause unwanted swings in water chemistry. This product safely boosts KH to help maintain a more stable and fish-friendly environment, particularly important for species that thrive with higher hardness and pH levels. It dissolves easily, is free from phosphates and nitrates, and one 180 g pack treats up to approximately 1500 litres of aquarium water. To use, dissolve 6 g (about one level teaspoon) per 100 L to raise KH by roughly 2 dKH, taking care not to increase KH by more than this in a 24-hour period and regularly testing water parameters for best results.
