Why Potassium Turns Your Pond Into a Chemical Experiment (And How to Keep It Balanced)
Understanding why potassium behaves differently than other nutrients in your pond starts with a simple chemical equation: 2K + 2H₂O → 2KOH + H₂. This balanced equation reveals what happens when potassium metal contacts water, producing potassium hydroxide and hydrogen gas in a vigorous, sometimes explosive reaction.
Before you panic about adding potassium to your pond, know that the potassium in fertilizers and pond treatments exists as stable compounds, not pure metal. When potassium sulfate or potassium carbonate dissolves in your water garden, it simply breaks into harmless ions that plants absorb. The dramatic reaction …
