Spring Restart of Koi Ponds: An Expert Guide to a Successful Season

Spring is the most critical time of the year for garden pond owners. The transition from the dormant winter phase to the active growing season brings with it a biological instability that we call “spring syndrome”. The right timing and work process determine whether your pond will be crystal clear during the summer or turn into an opaque “soup” full of algae and sick fish.

Filamentous algae and green water in a garden pond

Algae are a common part of any aquatic ecosystem. When in optimal balance, they improve water quality and provide food for some microorganisms. However, if they grow beyond their natural limits, they can become a problem — most commonly in the form of filamentous algae and green water. These two forms of algae differ in their nature, requirements, and even methods of control.
