Fall pool closing tip:
Balance the your water chemistry approximately 3-7 days prior to closing the pool.
Adjust your water balance within the ranges below: pH: 7.2-7.6, alkalinity: 80-120 ppm, calcium Hardness: 180-220 ppm
Next shock your pool with a chlorine shock or a non-chlorine shock, (at least 1lb. per 10,000 gallons-follow the package directions).
Allow the chlorine level to return to 1.0-3.0 ppm before adding any winter algaecide and your pool cover. Call us if you have questions!
