I live in a place where we keep our pools open year round. I think i understand how to balance a pool during winter. However - my go to place for liquid chlorine (Walmart) just put Xmas decorations in the outdoor section , is sold out of LC and put all their pool remaining pool toys, brushes, etc on clearance. This tells me I won't see LC there until next season... Sooo... where do people in southern climates get LC during the winter? Do I just switch to standard bleach during cooler months?
