ショック・藻防止剤・冬季保護剤・pH・アルカリ度調整の薬品量を計算します。
Enter your pool volume, current free chlorine, pH, and total alkalinity. The calculator recommends all the chemicals needed to properly winterize your pool, including shock, algaecide, and a winterizer dose.
Shock raises chlorine to 10 ppm to kill bacteria and algae before closing. Algaecide prevents algae growth over winter. The winterizer provides slow-release protection for 3–6 months under the cover.
If pH or alkalinity are out of range, the calculator includes adjustment doses. Balanced water over winter prevents corrosion of pool surfaces and equipment. Always run the pump for 1 hour after adding chemicals before installing the cover.
