Hey guys new to here and to aquarium keeping. I have a 75gal tank that has been running flawlessly for about 6 months now except for algae growing on the glass cover. I clean it off whenever I notice it building up and it's more of a nuisance than a problem. Any ideas on what I can do to prevent this? The algae doesn't affect anything but the amount of light that gets into the tank and makes it have a green hue.
