How to Open Inground Swimming Pools

Note: If you have a mesh safety cover on your pool, peel back the cover about a month before you plan to open and add shock. Mesh covers allow debris and sunlight to reach the water, and the pool can quickly turn green without pre-season care.
1) Remove the cover
  • Clear leaves and other large debris off cover
  • Pump standing water off of cover
  • Drain and store water tubes
  • Pull cover off; wash, dry, and fold for summer storage
2) Raise the water level
Add water to the pool until it reaches 1/2 to 2/3 of the way up the skimmer
3) Remove winter plugs and gizzmos
Replace return outlet fittings and skimmer baskets
4) Turn on filter system
  • If you did not clean the filter when you closed the pool for winter, clean it now
  • Prime the pump, and switch on the system
  • If you own a DE system, add new DE powder
  • Check the system, Is the pressure gauge working? Do you see any leaks?
5) Assess the pool
  • Remove large debris with a net; vacuum up dirt, algae, and small debris
  • Add shock at a rate of 1 gallon or 1 pound of shock per 10,000 gallons of pool water
  • Add a dose of algaecide
  • Add chlorine tabs to the chlorinator, floater, or skimmer basket
As soon as possible, bring a sample of pool water to Splash Pool Supply for a detailed analysis. After the winter, all of your chemical levels will probably be low.
