Though water gardens and koi ponds are two different types of water features, they are not exclusive to each other. In other words, just because you have a koi pond does not mean that you are forbidden from putting plants in your pond or stream, though most do not. Just the same, having a water garden does not mean that you can't put koi in it. Having said that, a water garden not designed to habitat koi will inevitably have problems if koi are put in it. Such problems may be dirty/cloudy water, inadequate filtration (resulting in a smelly pond or dead fish), and green water. We design all of our water gardens to be wonderful habitats for koi and all other pond fish. Good water garden design should entail complete circulation, aeration, mechanical and biological filtration, and last but not least it should be pleasing to both look at and listen to. And equally important, your water garden should be easy to maintain. To thoroughly understand our water garden filtration click here. A koi pond is a different breed all together! A good koi pond should be four to six feet deep with a conical shaped bottom. It should be as round as possible for your environment. And it should have extensive filtration, with the returns both above and below water level. Well designed koi ponds should also be covered with some sort of structure, such as an arbor, pagoda or what ever fits your taste and budget. This structure will provide protection from both the sun and from prey. Photo Gallery
