I would suggest changing your filter sock more often than that, I change my filter sock once every 2 days. Helps keep water clean and dusty mess off the glass. I think after a week of the same stuff running through the sock will cause these algae outbreaks. Like your feedings, you may do your water changes and not detect anything on tests, but you have leftover food sitting in that sock for a week! Not good for water to constantly run through. I have 6 filter socks, changing every other day. Once the sock isn't completely white for me, I change it.
