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.

Lifespans vary by material and manufacturer, but pond liners last anywhere from 10 to 75 years. For example, polyvinyl chloride (PVC) pond liners have a life expectancy of up to 20 years. Other types of pond liners, including those made of high-density polyethylene (HDPE) and ethylene propylene diene monomer (EPDM), can last 40 to 50 years.

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.

The average pond maintenance cost is $2,000. But how much you pay to take care of your pond depends on multiple factors, such as the size of the pond and whether fish live in it. Your area's climate also affects the overall maintenance cost, as you may need to winterize your pond to protect it and any aquatic life in it during the colder months.
