Green in ground pool

Hello! My family and I struggle every year with green algae in our in ground pool. It is a 18 x 36 4-9 ft deep with slope (rectangle) . We have tired every chemical that we have been told to use. I’m just not sure we are going about cleaning it the proper way. Could you please help me understand and get a nice clean and clear pool again!
