Garden fountains stationed in ponds are oftentimes far more than cosmetic devices. A pond, though it may be human-designed, does represent a viable ecosystem. In any ecosystem, there are niches created where various types of life might take root. Among the undesirable types where garden ponds are concerned is algae. A garden fountain provides the type of circulation that cuts down on such opportunistic organisms. Other types of fountains are more ornamental.
In very large ponds, one will often times see a garden water fountain working hard near the center of the water. These fountains are providing air to the water. In those ponds where fish make their homes, this has obvious value. It also agitates the water and keeps everything circulating and moving, which helps to keep the water clean. A good garden fountain set up in the correct way is actually a labor-saving device in that it cuts down on the amount of time one must spend cleaning and otherwise maintaining their pond. Some of these fountains, and some of their brethren, are solar powered. This makes them much easier to maintain and, especially at the center of a pond, it makes it much easier to provide power to the device. These are available for standard garden applications, as well, and are very popular.
A garden fountain can found in the aforementioned applications are not the only types on the market. Some are completely ornamental. These garden and pond fountains are oftentimes self-contained, requiring no pond or other water source beyond their own reservoir. These fountains are oftentimes added to a garden landscape simply for aesthetic reasons. When gardeners want something a bit more dramatic than a simple fountain, there are several different options. There are multi-tiered fountains that can make fine additions to any pond. There are also simple waterfall fountains that can provide excellent aeration while offering a subtle, relaxing effect.
Installing garden water fountain features can be very simple or very complex, depending upon the size of the fountain and the pond. In large ponds, there will be little concern regarding evaporation but, in most cases, this will be an issue. Most pond fountains either draw their water from the pond itself or are set up separately, with their own water source. Remember that water will evaporate more quickly outside than it will in the case of an indoor fountain. If the fountain has its own reservoir, check to make sure that a suitable amount of water is always present in the fountain and in the pond, if needed.
