The key to a low-maintenance pond or water garden is planning. How difficult will it be to maintain? If you follow a few simple guidelines, your maintenance requirements should be minimal.
Location, location, location
Locate your pond in an area that allows water to drain away from it. Ground runoff can cause major pond water quality issues because of lawn fertilizers, pesticides, and other ground contaminants. Also, note the accessibility of services such as electricity and water. If these services are not already near your pond construction site, you may need professional installation help.
Cut down on cleaning
Use pond plants to help improve water quality. They compete with algae for nutrients and help shade the water surface from direct sunlight, which also helps limit algae growth. Visit LiveAquaria.com for all of your planting options.
Maintain pristine water quality
If you'll keep fish in your pond, take care not to overstock. Estimate 1"-2" of fish per square foot of water surface area as a stocking measure. Although this formula works for small to medium fish, it is inadequate for larger fish. For example, a 30" koi can produce more than ten times the waste produced by 15- 2" koi.
Do not overfeed your fish. Feed only the amount they consume in 5 minutes. This helps keep your system balanced and your water clean.
When correctly planned, your pond or water garden requires only occasional cleaning, as well as infrequent equipment and water level checks. You'll spend less time on maintenance and much more time enjoying your backyard sanctuary.
