Bicarbonates (KH) buffer the water against pH changes. But via biological processes in the water the KH value and the pH value can change over time. Because all the life in aquariums and ponds is very sensitive to changes in the pH value a regular control method (i.e., water changes) to stabilize KH value is required.
