Simon's advice
At least 1 water lily
Without Water lilies , your pond Water lilies a greenhouse
Not enough shade on the water = an algae bloom caused by heat and light
Water too hot
Without shade, the temperature rises quickly. Warm water is a breeding ground for algae and retains less oxygen.
Too much sunlight
Direct sunlight provides algae with the energy they need to grow. They multiply rapidly in clear, unshaded water.
Fish have no place to hide
Herons and cats can easily catch your fish. Without water lily leaves, they have nowhere to hide.

The combination of heat, light, and nutrients will turn your pond green in a matter of days. Algae will take over.
