May is the time when most people in our area open their pools. The longer you wait the harder that chore might be. Pools that are opened fairly early tend to have much less algae than the ones that are opened after the weather warms up. Algae love stagnant, untreated water. So get started soon and enjoy that first warm weekend of summer swimming. Sign up to have the professionals at Aqua Pool & Spa Pros open your pool.
