Traditionally, pools are constructed using concrete and fiberglass, but this requires a separate filtration system to keep water clean and clear. Using materials such as gravel and clay can offer natural filtration that helps to purify water without consuming any energy or releasing toxic chemicals. Aquatic plants also help to filter water while also providing the oxygen needed to support the growth of beneficial bacteria and underwater life. Not only do small fish add a charming touch to natural pools, but they can also help to control local insect populations during warmer months.
Moss filtration is another popular method used to naturally clean pool water. Moss naturally traps dirt, debris, and microorganisms that can dirty up a pool’s water, reducing the need to use chemicals. Using moss also helps to conserve water, as homeowners need to backwash their pool less frequently.
