A backyard pond can be a beautiful oasis where you can sit and relax after a hard day of work. You can sit and watch the fish gliding lazily through the water, or just listen to the gentle sounds of the water. The best ponds are a balance of aquatic plants, colorful fish, and bacteria. The pond is a small ecosystem, consisting of many elements all in balance with each other. If the pond is out of balance, then the fish and plants may get sick and even die. Because of this, you’ll want to take steps to keep the pond in balance, and keep it healthy. There are a lot of things you can do to keep your pond healthy, but these five things are probably the most important steps to keeping a balanced, healthy pond.

Most residential water supplies have chlorine in them, which can be toxic to the fish. You will want to be sure to remove the chlorine from the water before you add any fish to the pond. You can buy kits at your aquatic supply store to remove the chlorine, or you can simply let the water sit for a couple of weeks to allow the chlorine to dissipate naturally. After this, you should test the pH of the water before adding any fish. The pH should be around 7.0.

Don’t crowd your pond with too many fish or plants. The more crowded a pond is, the more waste there will be for the filtration system to deal with, and you’ll find yourself doing a lot more work in maintaining everything. Also, too many fish and too many plants will remove too much oxygen from the water, creating an environment that will be prone to algae.

You’ll want to shade a good portion of the pond’s surface. Around 70% should be covered by plants to give the fish a place to shelter from the sunlight. Shade also keeps sunlight from reaching the pond, and causing algae growth. A portion of the surface should be open, however, to allow the fish to receive some sunlight.

You probably will want to add your fish to your pond right away. Don’t. Let the pond run for one or two weeks to allow the ecosystem of the pond to begin to develop. Some bacteria are necessary for the filtration system of your pond to work effectively, and waiting for a while before adding the fish will allow this bacteria to develop, and get established. When you do start adding the fish, don’t put a lot of fish in at once. Add one or two fish, then wait a week or two for the pond to adjust, then add some more fish.

You’ll probably experience some algae growth in your pond at first. Leave it be for a few weeks. This algae is normal, and the pond should resolve this situation as the ecosystem develops and comes into balance. If you still have a problem with algae after a few weeks, then you can take steps to reduce or remove the algae from the pond.

If you follow these steps, then your pond will be a balanced, harmonious ecosystem, where the plants and fish can thrive, and be healthy. A healthy pond will give you much more enjoyment, with much less effort.
