Q: How many years does a pond liner last?

• <div><p>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.</p></div>

Q: How often do you need to clean a koi pond?

• <div><p>Deep clean your koi pond at least once a year to keep your fish healthy and your pond in good shape. Water testing, debris removal, and partial water changes should be performed weekly. Seasonal professional service will ensure everything is clean and functioning properly.</p></div>

Q: Do koi ponds increase home value?

• <div><p>A koi pond may add value to your home if it&rsquo;s a feature sellers are looking for. Like pools, ponds can affect your property value depending on their condition, whether they&rsquo;re a popular selling point, and how well they&rsquo;re incorporated into your home&rsquo;s landscape.</p></div>

Q: I don’t want to dig. Can I build an above-ground pond?

• <div><p>If you&rsquo;re wondering how to build a pond above ground, it&rsquo;s similar to building a pond below ground.
