In New England, opening a pool correctly is super important because the winter weather can mess up your pool equipment and structure. If you don't take care of your pool early in the season, it can get all gross with algae and bacteria, making it unsafe to swim. Plus, opening your pool early means you get to use it for a longer time and get more bang for your buck. If you don't do it right, you could end up with a closed pool for way longer than you want, and nobody wants that. So, do yourself a favor and open your pool the right way for a summer full of fun and relaxation.
