charaChara Algae are cylindrical plants that grow under fresh water. They have a grainy feel.

Filamentous Algae (pond scum) is a quick growing algae that form mats that float on the water. This algae can begin growth in pond water with less than 3 feet of water and where sunlight can penetrate to the bottom.

Panktonic algae (known as pea soup algae or green water). It floats on top the water without forming a mat causing the water to look greenish, brown or a red like color. It grows quickly and is called an "algae bloom".
