Pool Opening Checklist: Everything You Need for Spring Season

Pool opening season is here. Whether you do it yourself or hire a pool service, following the right sequence prevents equipment damage and gets your pool swim-ready faster.

Step-by-step pool opening procedure

• Remove and clean the pool cover (store it dry)
• Remove winterizing plugs from return lines and skimmer
• Reinstall drain plugs on pump, filter, heater, and chlorinator
• Fill pool to normal water level (mid-skimmer)
• Reconnect pump, filter, heater, and all equipment
• Prime the pump and start circulation
• Remove any winterizing chemicals or antifreeze from lines
• Run the system for 24 hours before testing water

Water chemistry targets

• pH: 7.2-7.6 (test first, adjust with pH Up or Down)
• Chlorine: 1-3 ppm (shock the pool with 1 lb per 10,000 gallons)
• Alkalinity: 80-120 ppm (adjust before pH)
• Calcium hardness: 200-400 ppm
• Cyanuric acid (stabilizer): 30-50 ppm

When to hire a pool service for opening

Consider hiring a professional if: you have a variable-speed pump you're unfamiliar with, your pool was not properly winterized, you see algae growth under the cover, or you have a saltwater system that requires calibration. Professional pool openings cost $200-$400 and include chemical testing and balancing.
