Aquarium - KH Up, pH Stabiliser

KH up pH stabiliser
PFK award

Increases KH to Prevent pH Fluctuations

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.

Always test your water using Aquarium Lab test kits.
