Guide to Pumps
Like any pool, a natural pool needs a water pump in order to move water around the pool and through the biological filter and plumbing system. Pumps come in two basic types: Above Ground and Submersible. For a natural pool or pond that is intended for swimming, you will need an above ground pump, also known as an "in-line" pump. For a non-swimming pond, waterfall or fountain feature, it is okay to use a submersible or in-water pump. Submersible pumps are typically housed in a pump vault or within a large skimmer, while above ground pumps are housed in an enclosure that is separate from the water feature.
Once you know what type of pump you need, sizing that pump is your next step. Pumps come in many different power levels to turnover different amounts of water at varying speeds (displayed in horsepower, gallons per hour or gallons per minute). For a natural pool, this is very important to get right so your biological filter will work correctly. For more information on pumps, including how to correctly size one for your project, see the design resources available at The Natural Pool Academy.
