Fountains questions, answered by experts

In addition to length and width, pond liners also come in various thickness levels. Thickness is measured in mils, a unit of measurement equal to one-thousandth of an inch, with most pond liners ranging from 15 to 60 mils in thickness. The smaller the number, the thinner (and weaker) the liner. To prevent rips and tears, it’s best to choose a pond liner that’s at least 30 mils thick.

To maintain your pond, you’ll need to occasionally clean your backyard pond, especially if you have koi fish. Test the water twice a week to make sure your fish have everything they need and always remove visible debris.

Fountain maintenance is an important part of having a clean foundation in the first place. To keep your fountain water clean, you can use a water additive designed specifically to limit scale, algae, and other buildup in fountains. Or opt to use white vinegar as a pantry-ready water additive.

Backyard water features can add serenity to your property, drown out neighborhood noise, and serve as a focal point to a stunning landscape design. In some cases, a properly installed and maintained water feature can add to your home’s value. Just be sure to check with your insurance company before installation since some features may affect your premiums.

One reason you may want to fill in your pond is the cost of maintenance. Pond cleaning may cost about $1,000 for an annual cleanup, or monthly visits may cost $75 to $100 per visit. If you don’t want to spend that much per year on pond upkeep, you may consider filling in your pond.
