Optional island ring of plants: individually customizable with plants to  ensure Koi Pearl blends perfectly into the pond environment

Constant temperature: the same water temperature is maintained both inside the dome and in the pond, even on hot days.

Provides shade: the fiberglass support ring decorated with plants  provides extra shade for the fish.

Frost-proof: in the winter, you may leave your Koi Pearl in the pond. It helps you to prevent the pond from freezing over completely

Simple assembly and disassembly: Koi Pearl does not require a mounted  frame, thus preserving your pond liner. Check out our assembly film!
