My 55 gallon tank is getting way to over run with green algae. I have some plants in there but not a whole lot. some wisteria, hornwort and those apongonton or something like that bulbs from walmart. I had the ottos in there but they weren't really eating the green algae. they loved the brown algae in the smaller tank I moved them to for breeding... My question is is there a way to help cut back the growth of the green algae

The tank does get natural light during the day but not direct. What can I do cause that stuff is a pain in the butt to get off the tank.....
