No algae problems! The tank gets direct sunlight only for a couple hours during the morning in the summer. The other seasons, the sun doesn't reach it. I scrape algae every 2-3 weeks, but it's a very light layer on the glass and nothing major. It's a very low light tank. I was surprised at how little algae grows, actually. I feel like I really lucked out with the position/location of it too.
