Koi ponds and water features in Melbourne
Melbourne has a thriving koi club scene and some excellent specialist pond builders who understand the local seasonal conditions and council requirements across the many different LGAs.
Melbourne climate considerations for koi ponds
Melbourne's variable climate — four seasons in one day, cold winters, hot summers — requires specific pond design considerations. Koi slow their metabolism significantly in winter when water drops below 10°C and largely stop eating. This means your filtration system needs to handle very different loads across the seasons. Summer heat events (40°C+) can stress fish in shallower ponds.
