endless rain I open my pool about the same time that a two-week period of rain began. My land is turned into a water world. My pool collects worms, crawdads, and garden snakes. I worry that algae will begin, so I keep my chlorine levels above-normal. My pool is 12 feet by 60 feet. I chlorinate with liquid chlorine, baking soda, and soda ash. Is there anything I should be doing to prevent the onset of algae
