If your pool looks more like a swampy mess than a magical oasis, this guide will have you relaxing in crystal clear water in no time.

Instructions

• TIP: The best time to shock the pool is in the morning since sunlight will break down the added chlorine. Wait at least 24 hours before using the pool.
• Step 1: Add clear-water chemicals so your filter can remove the very small particles that make the water look cloudy.
• Step 2: Test the water one last time to make sure everything is within normal levels, and then dive in.
• FACT: The Nemo 33 in Brussels, Belgium is the world's deepest pool at 105 feet.
• Step 3: Shock the pool after a hard rain or heavy use to maintain proper chlorine levels and prevent bacteria and viruses from growing.
• Step 4: Feel the sides of the pool. If they're slimy or slick, add an algaecide.
• Step 5: Test the water using a water test kit. This will let you know how much of what product to add.
• Step 6: Add the proper amount of chlorine using a chlorine floater.
• TIP: Always wear gloves and old clothes when handling pool chemicals.
• Step 7: Skim and vacuum your pool, removing any debris floating on the water surface and on the pool's floor.
