so i have had the lights off for a few months now but i have small brownish green spots forming all over the rocks and equiptment. what should I treat it with before it gets worse? i wanted to turn the lights on soon but if its going to escalate the growth i wont. I do have a window near it but its a good 15 feet away from the tank. So its not direct sunlight but it still gets that natural light if i have the shades open. Ive been keeping it closed becuase the aglae seems to be thicker on the side that gets light.
