Locey Swim & Spa's knowledgeable staff members help people keep their paddling puddles clean and ready for activity with a wide array of chemicals and accessories. Dissolve Durachlor granular chlorine ($89 for 20 lbs.) in pools to keep aqua clean and clear, or sic Locey Swim & Spa's own nonchlorine Clear & Swim oxidizer ($79 for 12 lbs.) on feral packs of bacteria, contaminants, and algae. Locey's selection of water games and toys includes Aquaria pool floats ($89) and jumbo noodles ($11), which keep bodies buoyant in belly-flop-induced squalls. The aquatic authorities at Locey Swim & Spa will also hand-test water for free and craft a custom chemical routine to keep water as clear as an eloquent jellyfish.
