Yeah thats almost certainly one of the sources if not the primary source of your algae problem. 6-7 months is about 5-6 months too long lol. Canisters require weekly maintenance and changing of media almost as often or atleast rinsed or they become nutrient traps and turn into nitrate factories. Nitrates and phosphtes being what causes algae.
Also some fresh carbon would probably clear your water up in no time.
