Phosphate In Pools And Spas. Phosphate must be monitored because it is undesirable in pools and spas as it promotes the growth of algae. This is especially important for outdoor pools and spas. The level of total phosphates in pool and spa water should be 0.01 mg/L or below. Other key tests for pool and spa include pH, chlorine and turbidity.
