Choosing the right pond equipment

The right equipment, sized properly, does most of the work of keeping a pond clear and healthy. Undersized pumps and filters are the most common cause of murky water and stressed fish, while oversized equipment wastes energy.

Start with the two pieces every fish pond depends on:

  • Pond pumps: how to size a pump for your pond's volume and features, and choose between submersible and external types
  • Pond filters: mechanical and biological filtration, how to set up a filter and how to clean it without killing beneficial bacteria

Then add what your pond needs:

Use the pond calculators to work out your pond's volume, pump size and liner size before you buy, and see Water Features if your pump will also run a fountain or waterfall.

Common questions

Most ponds with fish need a pump, a filter, and either a liner or preformed shell. Many owners add a UV clarifier for green water, a skimmer for floating debris, an aerator, and a de-icer or air pump for cold winters. Our supplies checklist covers the rest.

A common guideline is a pump that circulates the whole pond every one to two hours, or every hour for koi, and more if it also feeds a waterfall. Check the pump's flow rate at the height it has to lift water, not just its maximum rating.

Quality EPDM liners can last decades, while pumps typically last several years depending on use and care. UV bulbs lose strength and usually need replacing every year, often in spring.
