Step 5: Laying the base for the Koi pond

Step 6: Constructing the pond
The pond is constructed with cement and bricks to ensure strength. It is recommended to build the pond 40cm above the water level to ensure safety for Koi fish. The best construction ratio on the pond's surface is approximately 15cm to 25cm above the ground. This helps ensure the Koi pond is protected from rainwater runoff.
