Koi pond is certainly the most beautiful version of the pond and almost every fish lover has a desire to build their own in the backyard. In fact, you will waste the most time building your pond. Maintenance is much simpler and requires only a few minutes a week of work and that refers to rinsing the pond filter. Koi ponds are truly special. You will not find gravel or stones inside them as this can harm the fish.
Also, the undersides of the pond are completely flat to protect your fish from various predators. They are mostly built of concrete blocks to keep the ground out of the pond. The average depth of the pond is about 5 'to 6', and the minimum depth should be greater than 4 '. The water is brought to the pond by an external pump, and there are no high-voltage electrical devices in the water.
