Are swimming pool waterfalls a good idea?
Absolutely! Not only do they look great and create a gorgeous aesthetic visual appeal, but pool waterfalls can actually help with temperature regulation due to the constant movement of the water. More oxygen is created which helps keep the average water temperature cooler than if the water stayed still, particularly in hot weather.
In addition, since a waterfall constantly moves the water, it reduces the chance of algae growth and buildup among the walls and bottom of the pool.
