can't say any more than what bluesamphire has said. You could scrape the sides and back with an algae scraper or a green scrubby. But again I would do this when doing a water change. If you just loosen the algae and not remove it from the tank it will just grow back faster and thicker. Reduce the light source to 6 hours a day and do a couple of 50% water changes to reduce the nutrients. With no live plants in the tank you could use Algiflex which will rid the tank of algae for sure, but you could also add a mystery snail or nerite snail to the tank and let them have at it. It's slower that way but it's natural.
