I take it back not planaria, not sure what it is, did it just appear from nowhere or has it been building up for some time?
I suggest a wipe and vac session, wipe away with an algae magnet or similar and vac it away (preferably without the syphon, just the hose end) and you should get rid of a lot of it, if it comes back keep doing the same thing.
Cut back on feeding too, if it is alive, then it needs a food source.
