Public parks, hotel lobbies, malls, restaurants and subdivisions have also added pools that are highly dramatic and artistic. Pools are actually miniature aquatic environments and are complex environments with both plant and animal life being important. Pool location is critical not only for the enjoyment of the viewer but also for the maintenance and health of the plants and animals in the system. Pools should have a minimum of six hours of sunlight each day. The sunlight is required for photosynthesis by the aquatic plants, including phytoplankton, which produce oxygen within the pool.
Abundant oxygen is required for a healthy environment for fish and other organisms within the pool.
It is best to locate your pool to avoid direct sunlight during the hottest part of the day if you live in an extremely warm environment. Fish can be stressed at high temperatures unless some degree of shade is furnished. As water temperature increases, the oxygen-carrying capacity of water decreases. Low dissolved- oxygen fishkills are more likely at high temperatures. Many individuals try to locate the pool within view of the home.
