KH value in ponds: why testing only distracts you

Discover why monitoring your pond's carbonate hardness is often unnecessary with the right insights.

KH value: the invisible hero of your pond balance

In the world of ponds, much revolves around GH and pH, but after 35 years in the business, I have discovered a crucial truth: the invisible force is the KH value, or Carbonate Hardness. Many people ask, "What is a good KH value?" and "Which is more important, GH or KH?". Here's the answer: an ideal KH value is between 6-10 DH. But the magic is not the number itself, it's about bringing the pond into natural balance. KH is the key to stabilizing your pH, which is crucial to the well-being of life in your pond. As carbon dioxide levels increase, KH adjusts quickly. So in the question "GH or KH?", I would say both are important, but the underrated superpower is definitely KH.

Understanding and treating: KH value aquarium and pond

"What to do when KH is too high?" This is a common question, and the answer does not lie in commercial remedies such as KH+. These solutions address the symptoms, not the cause. Striving for that ideal KH value is important, but don't get obsessed with numbers. Obsessively measuring water values can be misleading. Instead, I recommend a holistic approach to pond care: proper design, adequate oxygen plants, the right bacteria, and a quality substrate. This approach will keep your KH naturally balanced, save you money, and create a healthy, vibrant pond.
