If there are no live plants, then expect some type of algae. Any light plus the nutrients will allow algae to grow. This is natural. Adding plants, especially fast growers as was mentioned, can work to keep algae minimal.
When it is green water, there is usually a very high nutrient content plus significant light. In other words, the biology is not balanced. How long is the tank light on? Are you over feeding? Are there too many fish for the volume? Are you doing regular weekly partial water changes of 1/3 to 1/2 the tank, and vacuuming the substrate at each?
