Q: Should a water feature be in the sun or shade?

• <div><p>Placing your water feature in direct sun can speed up evaporation, leading to pump damage and algae growth. Shade or partial shade serves as the ideal location for most water features&mdash;just watch out for tree and plant debris that may fall in and clog the pump. </p></div>

Q: What are some creative ideas for repurposing the area where the pool was?

• <div><p>After you fill in your pool, you can add trees and plants that help stabilize the soil. You might decide not to fill it in at all and find another use for the sunken area instead. A few ideas include creating a seating area or garden inside the empty pool.

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