Fountains FAQs, answered by experts

How many fish can call your pond home depends on the volume of the pond and the fish size. Your pond's filtration system also influences the number of fish that will thrive in a pond. A general rule of thumb is to have 1 inch of fish for every square foot in a pond that's 2 feet deep. Another rule of thumb you can follow is to have one koi fish for every 200 gallons of water or two goldfish for every 200 gallons.

You have several options for your pond by getting your yard ready for the winter. You can winterize your koi pond by ensuring it’s at least 5 feet deep so it doesn’t freeze completely, installing a pond heater or aerator and having it run at all times, and installing a deicer if temperatures are dangerously low for an extended period. You can also choose to shut down your pond for the winter by removing all the wildlife in it and bringing it indoors, cleaning out the filter and pump, and then covering the pond with a tarp.

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

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.

A koi pond should be at least 5 feet deep to keep the fish healthy and ensure they don’t freeze in winter. Koi fish are also known for growing large, so the more room you have, the better. A larger koi pond size will allow the fish to grow bigger than a smaller one will, and the more fish you have, the bigger the pond you’ll need.
