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.
