I'll try and get a pic up later but I'm not sure I'll be able to get one of the water. I originally thought this was BGA as it is forming sheets across most stuff. However, everything I've read on BGA doesn't say anything about little threads floating in the water. There are literally millions of the little buggers floating around. They are as thin as a hair and have ranged from 3-5mm. I did a big clean 2 days ago and the tank looked nice but this stuff has just gone ape now and it looks worse than before. They settle out into sheets of quite dark green which can be lifted off in big patches. I haven't found anything that sounds like this yet. Anyone got any ideas?
