Most of us probably don’t think much about algae until we go swimming or fishing in a lake or pond and there it is. Just because the weather is getting colder, summer’s algae colonies aren’t going anywhere. Instead they are building strength for next summer’s bloom. Their main diet is phosphorous.
Nutrients, like phosphorous and nitrogen, emerge from such unassuming fall pollutants like leaves, grass clippings and soil sediment, or from sources unseen like excess fertilizer on lawns.
