Thread algae can be combed out, literally. But it helps if you cook it first with a bit of H2O2 (hydrogen peroxide). One or two H2O2 treatments kills it off effectively. Check Giancarlo's article on H2O2 . There might be no need to trim it. But there is a need to find out why you are getting thread algae in the first place - perhaps it comes as a result of dosing Tropica Master Grow or Flourish or Iron? I found that increasing my K by dosing K2SO4 eliminated the thread algae that came about from my dosing TMG.
