Does fertilizer decrease the amount of water in a pond?

Fertilizer itself does not directly decrease the amount of water in a pond. However, when fertilizers are introduced into a pond, they can stimulate algae growth, leading to eutrophication. This process can reduce oxygen levels and potentially harm aquatic life, which may indirectly affect water quality and availability. Additionally, increased evaporation may occur in nutrient-rich waters, but this effect is generally minimal.
