It’s a good idea to start this process a couple of weeks before you would usually open your swimming pool for the season.

1. Change your sand completely and scrub out the tank if dirty.
2. Let the pool run for at least one day before bringing in a water sample.
3. Balance Alkalinity, pH, and Calcium Hardness (250ppm).
4. Baquacil level _______ Date _______ Initials _______
5. Add one (2lb.) bottle of Flip Out per every 10,000 gallons of pool water. Add one 3” chlorine tablet to the skimmer basket per every 10,000 gallons of pool water.
6. Circulate pool continuously for 3 days
7. Baquacil level _______ Date _______ Initials _______
8. If Baquacil level has not reached 0 yet, repeat Flip Out dosage above along with the correct amount of 3” chlorine tablets in the skimmer.
9. Circulate pool continuously for 3 days 
10. If Baquacil level has reached 0 starts shocking the pool nightly with 1lb. of Granular Chlorine or 1lb. Cal-Hypo Shock (NEVER LIQUID CHLORINE) for every 10,000 gallons of pool water – you must do this every night until the pool holds a chlorine level.
11. It is normal for the pool to turn a clear green color during this phase. It is a chemical reaction between the remaining Baquacil and the new chlorine being added to the pool. When the clear green color stops we know your pool has accepted the chlorine, and you may begin your normal chlorine maintenance.
12. You should, at this point, clean your sand if it was changed at the start of the season, or if you have a cartridge filter.

• Make sure to brush down any precipitate that has formed on the pool walls to avoid staining.
• It is not a bad idea to add a metal chelating agent at this point to remove metals from the water.
