The decision to build an indoor pond inside your home can completely change the mood of a room, introducing the pleasing sound of running water, the charm of aquatic plants, and if you so choose, the meditative presence of koi or other fish. Constructing an indoor pond can actually be much easier than an outdoor pond, since you do not have to deal with digging a hole and waterproofing the hole against seepage. With an indoor pond, unless you intend to do radical renovations, you will likely be dealing with an above ground tank that can be constructed to conform to the parameters of the room.
Depending upon your personal preferences and any potential limitations presented by the room you intend to build in, you can make the tank for the pond as elaborate as you like. It all depends on how much time, effort, and money you want to spend. Beyond that, the sky’s the limit. Beyond the shape of the pond itself, the main concern when dealing with the construction of an indoor pond is a quality filtration system, aeration system and pump. The filtration system will help to keep the water clean, removing waste and debris left behind by fish or plant life. The aeration system will help to keep oxygen flowing through the pond to help sustain animal life. And the pump will keep the water cycling through the two.
Another important thing to keep in mind when constructing an indoor pond is regular maintenance. You will periodically have to replace the water, so be sure your pond is located in an area where you can easily do so. This means convenient access to a water source for replacement water, as well as an easy way to dispose of waste water.
