Green scum can mean numerous different things depending on who is observing it. If it is stringy then its FA and often micoinvertebrates (fry food) are associated with the "scum mat". If it is a bluegreen algae then it will soon disappear as the water cools more. Not sure why small BG (fry) were associated with patches or clumps of bluegreen algae.
