I have been trying to get rid of this algae and it doesn't seem to be leaving. I am wondering if some of this stuff is even algae. From my understanding the brown stuff is diatoms related to low light levels. I have 1.23 WPG and i am not supplementing anything. I was supplementing organic carbon by seachem but i stopped to see if it would help the situation. The green stuff just started appearing latley.. and as for the white today was the first time i noticed it.
