How do I effectively implement a koi pond in my Japanese garden?
I'm excited about adding a koi pond to my Japanese garden design to enhance the tranquility and natural beauty. I currently have a space set aside and some ideas for layout, but I'm concerned about the water quality and how to maintain a balanced ecosystem for the koi. I've done some research on filtration systems and natural plantings around the pond, but I'm unsure about the correct depth and size relative to the overall garden design. I've never integrated a water feature before, so any insights on construction, filtration options, and maintaining healthy water would be greatly appreciated!
