Fountains FAQs, answered by experts

DIY kits exist, but professional installation ensures proper filtration, landscaping, and leak-proof construction.

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.

A good rule of thumb is to change 5% to 15% of your koi pon’s water every week. Partial water changes help keep your koi healthy, and replacing small amounts at a time prevents causing stress for the fish.

Pond installation costs typically range from $1,500 to $10,000. The final price depends on several factors, including the pond's size, the materials used, excavation requirements, and any additional features such as waterfalls, lighting, or specialized habitats for fish like koi.

While they’re popular and have a lot of pros, the cons of river rocks include the following:

  • River rocks don’t break down or provide nutrients to plants. 

  • These stones can get hot and scorch nearby plants. 

  • River stones may heat the surrounding soil to inhospitable temperatures. 

  • Rocks can block rainwater from seeping into the ground if installations are too thick or tightly packed.

Most downsides occur when using river rock as mulch in gardens and flower beds. However, you can still incorporate river rocks into your landscape as long as you use them in the correct ways.
