Every Green Pool Is Different
No two green pools are exactly alike. The level of algae growth, water chemistry, and condition of the filtration system all determine the treatment process. Michael's Pool Service Inc. begins every green pool cleanup with a complete water evaluation so we can choose the safest and most effective solution for your pool.
Not all green or discolored pools are caused by algae. Our Pool Learning Center explains how to identify yellow pollen, mustard algae, high phosphate levels, and other common pool water issues, helping homeowners choose the right treatment before adding unnecessary chemicals.
