PoolCheck® Phosphate. Because phosphates are the primary food source for algae, the more phosphate, the more algae. High phosphate levels can produce resistant algae and interfere with the sanitizing property of chlorine. Regularly testing for phosphates can help to ensure a properly maintained pool. Reliable results are available in 30 seconds.
