Q: Do natural pools get algae?

• <div><p>Yes, natural pools can get algae since they use the same filtration processes as lakes or streams. However, you can reduce the risk of algae by adding more algae-fighting plants and not installing your natural swimming pool in direct sunlight, as it promotes algae growth.</p></div>

Q: Should a koi pond be in the sun or shade?

• <div><p>Koi fish should be in the shade and can&rsquo;t be directly exposed to the sun.
