Winterization Kits Work Extremely Well
I use one of these 24,000 gallon kits with another kit for 12,000 gallons to cover my 39,000 gallon pool (comes out about right once water is drained below skimmer inlets). In conjunction with the Bioguard Floater Bucket (I use just 1 floater bucket). I can tell you that my pool openings come spring are a breeze now and very inexpensive- water is clear and not one trace of algae. This is my procedure from here on out!
